Whats up guys? just picked up a 2013 ST2, it came with a injen catback with titanium tips, lowered and a ford racing procal 2. I dont know much about the procal 2 or how to use it yet. Last month my wife and i traded in our BMW's mind was a 2006 325I Msport sedan, 6 speed man, wifes was a 2004 325. I got a 2012 xterra and she got the ST. We love the car so far, but it went back saturday because a check engine light came on, and it turns out it needs a new CAT. the dealership is fixing it and we should get it back wednesday. Been modding cars since I was 16, I am 32 now. This is my first moddified car with Boost though so i am very excited. Anything you guys can tell me about the car that i would need to know or how to use this procal correcty would be greatly appreciated. Thank you.
