So I bought a new 2016 ram 2500. Pretty quickly I decided to take it to a local shop to have an exhaust and tuner installed. I went with a flo pro 4" turbo back exhaust, had the egr and dpf deleted and they used the PPEI tuner on it. Ever since, regardless of what tune I'm running, the truck stutters at high rpm. It's almost like it's hitting a fuel cut. None of my other trucks in the past have done this and I can't figure out if it's the tune or another issue I'm having. Has anyone else experienced this or can maybe tell me where to start? Thanks in advance.

 

My advice would be to contact PPEI and discuss the situation with them. Kory Willis more than likely wrote the tune on that. I may still have his contact info i could try to dig up if need be
