Thanks. What nobody seems to realize is that I am not complaining that these mods failed to net me significant gains. Rather, I am bummed that my build is getting me 385 hp or less at the fly. I was really hoping to get at least 400. My torque numbers are there and I am happy with them (400 ft lbs at the rear wheels) I just don't understand why the hp isn't there as well. As for my elevation, I am at 9 feet below sea level. Sometimes a bit more.
