Hello i have a 2002 gts with an invidia n1 exhaust. i will buy an injen cai. i was planning to buy the apexi pfc from mwr with the injen cai map. I will be raising the rev limiter to 8500 and lowering lift engagement to 5800 like the reflashed r9k corolla xrs. What kind of gains should i expect ??
its okay and safe to run the pfc without a tune i dont have much tuners that work with the apexi pfc from where i'm from and dont wanna buy it if its not safe to run using the injen cai base map.
Will make a youtube video on it.
