I installed the 95hp tune from the bully dog power pup downloader and it ran great for a month and then the power slowly backed off over a period of time now it feals like the first or second tune. I even tried going back to stock for a while and then reprogramming still no change. Does the power pup defuel to protect the tranny? It has never gone into limp home mode, could the tranny be hurt already? The oil came out really dark purple almost black but it did not smell burnt. I talked to bully dogs tech, I could not get much info out of them they suggested there shift enhancer. I'm going to install that today but I here it is worthless is that true? Later I will upgrade the tranny when funds allow but for now I want the most power and reliability I can get.

Thanks

maybe your fuel filter is plugging up & dont bother with the shift enhancer

Hey Noreaster thanks for the reply but the filters brand new and I already wasted my time putting in the shift enhancer, I havent drove the truck since I installed the shift kit but Im sure it won't help much
