well, i bled all that air out of the coolant and put it on a dyno. without any tuning, it made the exact same #'s that it made from speed inc with just a cam. that was pretty upsetting. so we did some tuning, added some timing, leaned it out barely, and it made 370/379. that was also dissappointing. i thought it would easily make over 400 w/ these expensive heads. everybody at the shop was flabbergasted. well, i talked to tony mamo from AFR, we researched the minor details with the tuner, and pretty much came up with the notion that this is all the truck has, and thats all these heads should of made. tony said that my cam is such a baby cam, he wouldnt expect more than a 20ish hp/tq gain.
anyways, after comparing my baseline at this particular shop (fc customs) to the new dyno numbers, the gains looks pretty good. the baseline on their dyno jet was 288/299, so if you do the math on the same dyno, i gained 82 hp and 80 tq from a baby cam, AFR heads, headers, magnaflow catback and a k&n intake (soon to be replaced by a vector). i dont know if thats good or bad.
anyways, driving it is a lot more fun now. yea the numbers really pissed me off and were quite upsetting, but once i take off my dyno queen mask and drive it, its easy to notice the smooth torque that just pulls. sounds damn good with the cutout open (which only gained a couple more power open, by the way).
anyways, here are the graphs. baseline on the same dyno as the after with h/c. now i just need to figure out how to match my mods and make some real man power
