Twin turbo LS6 in a sandrail I'm building a high horsepower twin turbo LS6 in a sandrail and would like some advice on which computer you think I should run and why. I might be running over 15 psi. Pros and cons?
That would be pretty sweet but you will definitely have a hard time keeping the front wheels on the ground unless its a tube framed school bus for like 10 or more passengers. I would suggest a fast system or a rewired stand alone gm harness/computer. If your going ***** to the walls for cam and as wild as you can go and maybe more-so in the future, I would suggest the fast system.

I am going to try and tune this thing for 750 rwhp. I heard efilive just came out with a 2 bar program for the factory computer. I think I am going to try that since nothing else is better. Does anyone know the horsepower limits of the block itself (that's the only factory piece left in the motor)? any other motor input is certainly welcomed.

the first weak link in the block design is the 4 bolts per cyl... so ARP studs go a good ways fixing that..
as far as i know, no-one has cracked a stock block in half yet......

I have seen only one cracked block. It was a 1998 F body motor that #2 main bearing "spun". It tore up the crank, fried the bearing and caused a 4 inch long crack in the main web straight up toward the camshaft. It was a very heavy dose of NOS that contributed to the failure.
