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.

Does the tune fix rev hang?

On a manual, yes. The factory map holds the throttle open a crack when you lift off, so the revs hang between shifts. We change that as part of the tune, not as an extra job.

Is the FA24 reliable with more power?

Yes. The FA24 is a stronger bottom end than the FA20 it replaced. With sensible tune targets it'll handle a Stage 1 map all day.

Will this void my warranty?

Toyota and Subaru can deny warranty on related components if they detect the tune. RZ Stage 1 is the lowest-risk starting point: there are no hardware changes, and the map can be reverted to stock if needed.

Can I upgrade to RZ Stage 2 later?

Yes. The Stage 1 tune is the foundation; Stage 2 adds the aFe intake and Korsh headers with a re-tune for the new hardware. Money spent here isn't wasted.

How long will my car be with you?

Same day or overnight. Tune on the dyno, road test, hand back with sheets.
