TuneVault Pricing Explained: What $39, $19, $49 and $249 Actually Get You
A plain breakdown of every TuneVault plan — what a single guided tune includes, where each monthly tier makes sense, what the product does not do, and how to pick without overbuying.
By TuneVault
If you have landed here trying to work out what TuneVault costs and whether it is worth it, here is the whole picture without the sales language.
As of July 2026: one guided tune is $39 for a single vehicle. Monthly plans are $19 (Garage), $49 (Pro), and $249 (Shop). The full breakdown lives on the pricing page; this article explains what sits behind each number, which tier actually fits which situation, and — more usefully — what the product does not do.
What you are buying, precisely
TuneVault is a guided copilot for HP Tuners. It does not flash your car and it does not sell calibrations. What it does is sit between your tables and your decisions.
A session runs like this. You screenshot your VCM Editor tables — injector data, MAF or VE, spark, fuelling, rev limits. Vision reads them, values and units preserved. The audit then checks the whole set against each other and against the parts you say are installed, and flags problems with severity: red for critical, amber for caution, green for clean. You get an ordered change list with the specific cells and values, sorted safety first, with the reasoning and the unit traps called out. Then you flash, drive, and upload a VCM Scanner log, and the tool checks commanded against delivered air-fuel ratio, knock retard, fuel trims, and intake air temperature, and gives you a plain go or no-go.
The whole session is saved to the vehicle in your garage, so when you come back in three weeks you can see what you changed and why, and roll back to the last known-good state.
That is the product. It is analysis and guidance, not a file and not a flashing tool.
The four options side by side
| Per Tune | Garage | Pro | Shop | |
|---|---|---|---|---|
| Price | $39 per tune | $19 / mo | $49 / mo | $249 / mo |
| Guided tunes | One vehicle, one time | Up to 3 / month | Up to 10 / month | Unlimited |
| Datalog analysis | One verification pass | Unlimited re-checks on your cars | Unlimited | Unlimited |
| Vehicles saved | The car you tuned | Your own cars | Multiple vehicles | Customer and vehicle records |
| Copilot | Standard | Standard | Priority — faster, deeper audits | Priority |
| Seats | One | One | One | Multiple technician seats |
| Best fit | One car, one project | Weekend builders | Active DIY tuners | Performance shops |
Two details in that table do most of the deciding.
Unlimited datalog re-checks are the reason Garage exists at $19. A first tune is rarely the last word — you flash, you log, you adjust, you log again. If you expect more than one verification round, the monthly tier costs less than buying repeat passes and removes the incentive to skip the check because it costs something.
Seats and records are the reason Shop exists at $249. A single tuner does not need them. A bay with three technicians tuning customer cars needs a shared safety checklist and a record of what was done to whose vehicle, which is a different problem from tuning your own truck.
Which tier actually fits you
One car, one build, and you want to see the output before committing. Buy a single tune at $39. It is the whole workflow including one verification pass, and it tells you within one session whether the tool's reasoning is useful to you.
A project car you are dialling in across several weekends. Garage at $19 per month. Three guided tunes covers a typical revision arc, and the unlimited re-checks mean you log after every change instead of rationing them.
You tune regularly — your cars, friends' cars, an e-tuning side business. Pro at $49. Ten tunes a month and the priority copilot, which matters when you are working through a queue rather than one file.
A shop. $249 with unlimited everything, seats for your techs, and a standardised checklist across the bay so the newest technician runs the same safety audit as the most experienced one.
If none of those obviously describe you, start at $39. Upgrading later costs nothing extra; buying a subscription you underuse does.
Where TuneVault sits against the alternatives
This is the comparison people actually want, so here it is honestly.
Against a custom dyno tune ($300 to $600 typically, as of July 2026): the dyno buys you controlled load, a repeatable environment, and a specialist watching your engine in person. That is genuinely worth the money on an aggressive build, an unusual combination, or anything running near the edge — see the supercharged tuning guide for where in-person work earns its keep. TuneVault does not replicate supervision. What it replaces is the guesswork on builds that do not need a dyno bay.
Against a remote e-tune: an e-tuner writes the file and you supply the logs, with days between revision rounds. TuneVault reverses the arrangement — you keep control of the file and get the analysis immediately. Which is better depends on whether you want to understand your calibration or want somebody else to own it. Our DIY copilot versus e-tuner versus dyno shop comparison works through the trade-off properly.
Against an off-the-shelf handheld: a canned file assumes your car matches an average. That is a reasonable assumption on a stock car with good fuel and a poor one on anything modified. The handheld also gives you no verification — nothing checks your car afterwards.
Against doing it yourself with no help: the honest answer is that plenty of people learn to tune well from forums and patience. What you are paying $39 for is the audit catching the mistakes that are expensive to learn from — a unit trap in injector offset, a lean spot at the top of a pull, timing that is fine on a cool morning and marginal in August.
The costs that are not ours
A complete budget for DIY tuning includes things TuneVault does not charge for and cannot waive:
- HP Tuners interface hardware. You need an MPVI to read from and write to the vehicle.
- Vehicle licensing. HP Tuners licenses per VIN, and credits are consumed when you license a new vehicle. Our coverage and credits article explains how that works and how to check your car before buying anything.
- A wideband oxygen sensor, if the car does not have a trustworthy one. Verification without a wideband on a modified car is guesswork.
- Fuel burned during verification pulls.
None of these are optional and none of them are hidden — but a price comparison that ignores them is not comparing the real cost of any path. The full cost guide puts every route side by side with those figures included.
What TuneVault will not do
Worth stating plainly, because the wrong expectation is the most common reason a tool disappoints:
- It does not flash your car. HP Tuners does that.
- It does not sell stage files. The stage 1 versus stage 2 explainer covers why those labels matter less than people think.
- It does not diagnose mechanical faults. A vacuum leak, a failing coil, or a fuel pump that cannot hold pressure needs a mechanic. The tool will tell you the log looks like a mechanical problem, which is useful, but it will not fix one.
- It will not tell you a tune is safe when the log says otherwise. The go/no-go is the point of the product; softening it would defeat it.
- It cannot make an unsupported vehicle supported. Coverage is determined by HP Tuners.
Getting a number for your car
The fastest way to find out whether any of this is worth $39 for your specific vehicle is to check where your current calibration stands. Start a tune to run the full guided workflow, or upload an existing log at scan if you mainly want the datalog verdict. If your situation does not fit neatly into a tier — a club buying several seats, an unusual platform, a question about coverage — get in touch and we will tell you straight whether the tool helps.
The bottom line
TuneVault is $39 for one guided tune, or $19, $49, and $249 per month for people tuning more often. What that buys is a careful read of your tables, an ordered list of what to change and why, and a verification pass that tells you whether it worked. What it does not buy is a flashing tool, a stage file, a mechanic, or a substitute for the dyno on builds that genuinely need one. Pick the smallest tier that matches how often you tune, and upgrade when you outgrow it.
Frequently asked questions
How much does TuneVault cost?
As of July 2026 there are four options. A single guided tune is $39 for one vehicle and includes the full table audit, the exact change list, and one datalog verification pass. Garage is $19 per month for up to three guided tunes and unlimited datalog re-checks on your own cars. Pro is $49 per month for up to ten guided tunes with unlimited datalog analysis and a priority copilot. Shop is $249 per month with unlimited tunes and datalogs, multiple technician seats, and customer and vehicle records.
What is included in one $39 tune?
A full vision read of your VCM Editor tables with the exact values and units preserved, a complete safety audit with severity flags on lean wide-open-throttle areas, aggressive timing, injector and airflow mismatches, an ordered copy-paste change list with the reason for each change, a risk score before you flash, and one datalog verification pass afterwards. It covers one vehicle and the whole session is saved to your garage.
Should I buy per tune or a monthly plan?
Buy per tune if you have one car and one project. Choose Garage at $19 per month if you are dialling in a build over several weekends and expect to revise the file more than once — the unlimited datalog re-checks are the reason that tier exists. Pro at $49 makes sense when you are working on multiple vehicles regularly. Shop at $249 is for a bay tuning customer cars where multiple technicians need seats and records.
Does TuneVault replace HP Tuners?
No. You still need HP Tuners hardware, the VCM Suite software, and the appropriate vehicle licensing to read from and write to your car. TuneVault is a copilot layered on top of that — it reads what your tables say, tells you what to change and why, and checks your datalogs. It is not a flashing tool and it does not sell calibrations.
Is TuneVault cheaper than a dyno tune?
Substantially, though they are not the same service. A custom dyno tune commonly runs $300 to $600 in the United States because you are renting the dyno, the operator, and a tuner's hours. TuneVault is analysis and guidance, priced from $39 per vehicle. For an aggressive or unusual build, in-person dyno work still buys supervision that software cannot replicate.
What does TuneVault not do?
It does not flash your car, it does not sell stage files, it does not diagnose mechanical faults, and it will not tell you a calibration is safe when the datalog says otherwise. It also cannot make an unsupported vehicle supported — coverage and licensing are determined by HP Tuners, not by us.
Can I switch or cancel a plan?
Monthly plans are managed from your account billing portal and can be changed or cancelled there. If you are unsure which tier fits, starting with a single $39 tune is the lowest-commitment way to see the output before subscribing to anything.
