Touge got the parts in during logistic nightmares of a pandemic…kudos. Install was easy, took 40 minutes for the SF intake. Access port was familiar already from my Evo. I fill with Petro Ultra 94 and as Cobb advises, I used the 91 ACN Normal Waste Gate map to start. Ran for a few days to let the ECU learn fuel trim, pulls resulted in a very linear power band hitting 18.2lbs at peak. I did not think I would notice much bit the car is just overall better now. Throttle mapping is vastly improved, and on this 19 Sti any rev hang is gone…let off the throttle and it immediately responds. If you and a 19 or newer Sti, this as a first mod is epic.
