Ok, so this is the first time I have made mods to my wrx, I will give you the run down of parts and the issue as I understand it. 2017 WRX with turbo back exhaust, Perrin FMIC kit, a BOV, misamota race intake, and a Radiator cover, that forces air into the intake and Cobb accessport. When ordering the parts the sales person told me I should be good to run stage 2 bf plus, so on my accessport I loaded stage 2 bf 93 304. The car cranked up fine, no check engine lights, I checked to make sure I had no air leaks and no unhooked wire harness. To the car out for a test drive , sounds great seems to have more power. As I let off the gas the car shuts off. I pull into a parking lot, check my tune to make sure I have the map that I was told, check for codes which there was none. Cranked the car and drove it back home. It seemed like as long as I was on the gas the car was fine. The second I let off to stop it seemed like the rpms would just drop to 0 and the car would shut off. When i got home i tested this, cranked it up and let it Idle, reved the gas and let out it shut off. Can you guys offer any pointer for me to look at?
