Well I may get grilled for this but here goes, truck is a 03 LB7 and has stock allison, intake exhaust and lift pump, running Korys max effort for the big tune, only for sled pulling. It is going to go to dyno tonight, and it is a dyno jet i believe, it is a no load dyno and my regular cab held the 150 tune no problem no limp. So do you think I will be able to dyno the truck in the big tune or will it limp?
