Car not hitting target boost
After successfully completing a manual swap this weekend, i went ahead and installed the 2-Step rev limiter and no lift shit. When i go to start the car, everything runs fine, so i check my jb4 for codes and it says i have a Faulty low fuel pressure sensor (29f3). I then disabled the jb4 and went back to stock tune and still got the code. JB4 and Backend flash worked before the swap. Im just thinking if the 2 step has anything to do with the fuel sensor at all. BTW 2-step doesnt work :/ even after trying to trouble shoot it using the install guide. Someone guide me through this please?

Man sorry to see you're still dealing with this. Did you test the car after the swap, but before installing the 2step?

Yeah I'd try that first and make sure it's not something else. If the issue stops with the 2step out then you know where your problem lies.
