thanks again HPtuners,
bought a 2000 silverado 2500 LD

cammed the stock motor, installed alum stock heads, ls9 gaskets, chinese heads studs, and pac 1218 springs, tick performance custom cam, twin 61mm turbos

then loaded in the custom 3 bar SD os with a EFI source 3 bar map sensor and been chipping away at it here.

another satisfied customer, looking forward to brushing up more of the tune and getting it on the dyno
