I have a f150 2004 with a wipple supercharger installed. I had it dyno'd (410 hp) and was told that it was starving for fuel around 3500 rpm and that I should have 39-48 lb injectors installed. I had 39 lb injectors installed and now I have no boost? the boost gauge reads
-10 at idle and -5 to -10 at WOT. No power, but it idles OK? What should I look for; could the by-pass valve be stuck ?
