Why custom tuning instead of a flash tune?

Flash tunes are generic files written for a 'typical' car. Custom tuning means we build your map from scratch on our dyno, adjusting for your specific engine, mods, altitude, and fuel. The result is more power, better drivability, and safer AFRs — because we're tuning YOUR car, not a template.

Is the FA24 turbo reliable with more power?

Yes. The FA24DIT is a strong platform from factory. With proper tuning and conservative targets, these engines handle increased power reliably. We don't chase headline numbers at the expense of longevity.

Will this void my warranty?

Modifications can affect warranty coverage on related components. A tune-only approach is the lowest-risk starting point — no physical hardware changes. Happy to discuss your specific situation.

Can I upgrade to RZ Stage 2 later?

Yes. Your Cobb Accessport carries over. RZ Stage 2 adds intake, intercooler, j-pipe, and blow off valve with a re-tune. You're not wasting money starting here.

How long will my car be with you?

Same day. We build your custom map on the dyno, validate with road tuning, and hand it back — all in one day.
