Why custom tuning instead of a flash tune?

A flash tune is a map written for a generic car off the production line. We build yours from scratch on our dyno, watching live data on your specific engine, fuel, and condition. The numbers come out higher and the car drives better. Because the map is for your car, not someone's average.

Is the FA24 turbo reliable with more power?

Yes. The FA24DIT is a strong unit from the factory. We tune to sensible targets. Chasing a hero number on the printout isn't worth a tired engine in two years.

Will this void my warranty?

Subaru can deny warranty on related components if they detect the tune. A tune-only Stage 1 is the lowest-risk option. No hardware changes, and the map can be reverted to stock. Talk to us if you're unsure about your specific car.

Can I upgrade to RZ Stage 2 later?

Yes. Your Accessport carries over. Stage 2 adds the Process West intake and intercooler plus an Invidia j-pipe with a re-tune. Money spent here isn't wasted.

How long will my car be with you?

Same day. Custom map on the dyno, road tune, hand back with sheets.
