here it goes, Ok ive been reading up on the banks big hoss bundle, it seems the max out put for the duramax maxes out to the same hp and tq weather it is a o1-05 why is this? im guessing that gm did tuning refinements and the moter is only capable of that power out put, the second is i was told not to run more than 50 extra hp through the alli or it will not last as long. so does that mean that my little lb7 300 hp can only be pumped up 50 hp so i dont hurt the trans or can i go 50 above the lbz i think is 325 so can i safely deliver 75 more hp to my lb7 and my trans will be ok or were the newer 5 speeds beefed up? I know! thats why i said confused or is the banks guy blowing hot air?
