finally got the truck on the dyno. put down 322hp & 344tq at the wheels. this was on a dyno dynamics dynamometer, in third gear with the converter unlocked, air/fuel ratio was around 12.2 @ wot. my sig time is with open exaust out the y-pipe. dyno run was with stock catback, tailpipe, and aerochamber.

mods are as follows...
mail order nelson tune, cai, tb bypass, ls1 fans, tr220/112, 918's, pacesetter lt's & ory, aerochamber, stock catback and tailpipe, built 60e, tci sf3000, 4.10's & eaton.

here's the dyno sheet. top line is torque, bottom line is horsepower
enjoy...
