I need some help with my 2001 Cummins. I have recently had some dead pedal issues with my truck and took my truck in to a diesel specialist and had him test my injector pump. My injector pump is fine according to him but he found that my waste gate was stuck on my stock turbo. While trying to free the gate, he noticed my turbo was cracked so I purchased a new after market turbo.

Last year I replaced the stock exhaust to a 4" exhaust, added a new lift pump (Raptor) and all of my guages.

So, while pulling my 5th wheel last weekend, I noticed some funny shifting patterns and sort of dead pedal syndrome. My friend told me his father in law had issues with his Superchip, I also have a Superchip so I disconnected it and no shifting issues anymore.

I still have no power though while pulling my camper. Contantly downshifting even on the smallest hills. My new turbo came with a plug to try and trick the map sensor so I installed that and I still have the 0234 code saying turbo boost limit exceeded. Is this why my truck has no power??

Anyone have any ideas of what to check or look at?

Thanks
