i have heard some piston failure with more then 550rwhp with the LBZ but it won't take much to hit 500rwhp(with the ppe hot et 2 you will hit in to the 490rwhp with the stock turbo and injecters)and with the 2500HD you should run in the low 13's and hit in to the high 12's and i wouldn't run more then 32 psi with the stock turbo and no more then 40 psi with the stock head studs..just my thoughts
