Only 32 PSI with 125s and compounds
First post, any help is appreciated. My truck is a 2001 5 speed 240,000 miles. Has a Fass 150, BD injection pump, Edge Juice w/ Attitude, and stock over (i think) ~S300 compounds. I just installed 125 horse BD injector nozzles and have gotten almost no power gain over the nozzles i just took out, which I am 90% sure were stock. If I pin it from 1200 RPM in first gear itll blow a short cloud of smoke but then quickly cleans up around 15 PSI. PEAK boost is about 32. Ive read on other posts that people are making that if not more with 60 horse injectors. When I bought the truck it had the juice box under the hood but someone had removed the screen. I then bought a kit from Edge that included just the screen and noticed a small increase in power. Something is telling me the computer is not dumping fuel like it is supposed to even on the 5x5 tune. From a roll in any gear the exhaust is completely clean. So my question is why is the truck not pulling hard with 125s and compounds and peaks at 32 psi. Thank you all, I find myself on this forum almost every week, so figured I go ahead and ask the experts.
