While I find the OP's dyno #s disappointing, and agree there's probably many factors there, I also think your #s are inflated, if you do the math, with ONLY 2 bolt-ons you're making 264whp.... with 15-17% drive train loss, that's 310-318 hp at the crank.. HAHH I don't think so man.. If that was the case, I have a y-pipe and catback and should be whopping stock altima coupe 3.5s.... which did not happen.Importroller wrote:Elevation definately played a roll, but the lower temps should have given a lil more increase.
