Ok i have researched everything i can on that worn out search button. I found a forum that is sum what close. there are alot of questions and i am turning to you (Dsm tuners)
Heres my problem. My car will not boost past 7 psi. Now heres the thing. it reachs 5 psi easy and takes a little time to hit 7psi. When hit 7psi it feels like the motor just shut the fuel off and wont go any further. I have a totaly upgraded fmu and welbro fuel pump. I have heard that the 420a engine has a fuel cutt off... this true? Do you think that im hitting that point? I have my mbc set to the fullest. I seen on a video, 3rd gear floored stays at psi. Shouldnt it boost 7psi when i floor it and am at 3500-4500? the car seems pretty quick for 5 but most i want to run is 10-12 daily(on new 330 injectors) and never touch this again cause im sick of all the problems. So im turning to you tuners to try to help me if you can or have an idea on what is going on.
Thank you for any one who puts there 2 cents in.
