I got an ap1 n recently installed a used comptech sc. The car stalls n feels laggy whenever I try to get on it. Hardware wise I got everything there but for fuel I'm only running fuel pump, fmu n fuel regulator. That was all that came with it. I'm sure it's missing something on the fuel side. If u guys know what I'm missing n where I can get it would be of great help. Thx

 

You need at least a AFR gauge so you can tell exactly whats going on. I wouldn't drive it until you know that the fueling is correct. You risk blowing it up
