Tyreboyz,
What am I gonna need for my LBZ to hit 400rwhp? All I have is 4" exhuast and no cat.

well first of a good shift kit or tranny upgrade is recommended but is possible to do it with out it...here is a bone stock LBZ with the ppe hot et2 pushing 490rwhp and over 900rwtqr,darn i can't find the right web page,but with a good tune you can hit 400rwhp somewhat easily....the best tunes avalible for this kind of hp is ppe and efi live...with what i've done to my LBZ it should be over 400rwhp seeing the stock 2500HD truck dynos 315rwhp...i can tell you better in about 2 weeks from now i will have the true facts on the hp...

found the web page....i said it was a stock truck well i had that info wrong he does have some other stuff on the truck so here you go enjoy it has some very interesting info http://www.thedieselgarage.com/projects/Chevy/6.6Dmax/6.6shootout.htm ..to get the best results for the ppe hot et2 you'll need a bigger fuel pump,fuel rail,a stage 4 tranny and a good torqu converter
