Hey guys whats going on, well like the title says, I dont think my profec b is working, I thought I had the boost controler set to 14 lbs, but sometimes when I hit the gas I hit fuel cut, and that just got annoying, last night I was doing some pulls just to set my controler right but boost spiked to 17lbs and of curse I hit fuel cut again, so I turned down all the knobs on the profec b, I did one last pull and I still was at 15 lbs of boost so that's why I think my probec b does not work, Im runing a small 16g now, what could be the problem? I will be doing a boost leak test on monday I'll see how that goes, Im just tired of hiting fuell cut almost all the time, I will also be instaling my 255fp and my afpr as well, I hope that helps since I dont have any fuel mods but still I don't think my profec b is working right, What you guys think? One last question, How often do you guys change your plugs??
