Supercharged Tuning

Supercharged & forced-induction tuning help

Boost is unforgiving. TuneVault reads your injector, MAF, and spark tables, flags lean spots and aggressive timing before they hurt your engine, and walks you through exact, copy-paste changes for a supercharged or turbocharged build on pump gas.

What you get

✓Catch lean WOT and dangerous timing before a boost pull
✓Injector + MAF scaling checked against your actual parts
✓Wideband-verified before you trust full boost
