Oh damn I didnt realize that the 01's had less Hp that the 03's man I learn somehting new everyday thanks for pointing that out to me! Im pretty sure I knew that the 01's werent as strong as the 03's stock Im almost positive! The reason I was sayintg is because I thought the mods that he had would generate more HP than they did! See were Im coming from know!!!! Smartass! LOL

249.7 hp and 256.0 ftlbs with UPD and HPP3 on 93 octane. Looks like u might be losing some power thru that converter or tranny.

Yeah the 4.10's arent on yet but they will be in a few days!!!!!!!!!!!!!!!!! When I dynoed it was like 92 degrees and humidity like 60% or whatever it is here in LA really humid though! What kind of difference do think I would see in say 50 degree weather???
