i installed a billitflow throttlebody and plenum today and did some dyno testing, i made sure iat1 and 2 matched as well as ect temps on every run so the testing would be fair, end results were that the tb gave me almost 6 hp and 1 ftlb of torque from 5800 rpm to 6500 rpm then i took the tb off and put my stock one back on for 1 more run and it made more tq thru the powerband and 2 more hp then the aftermarket tb , airfuel did not change at all on every run so there is the results take it for what there worth i dont have dyno graphs to scan in but other members saw the results as well, mods are 2.80 pulley, c&l meter, offroad h pipe and catback
