I'll be honest, but to be fair, I think my expectations were/are out of line. We mainly use the truck for hauling our 16k# 5er. My goal for the rollback was to increase our MPG from the 10ish to something higher and to make the truck run better overall. Many believe that the older programming was better than the newest code (which mine was on) for things such as MPG and low end power. Well....the MPG change didn't happen. However, after a reality check, I realized that with the load we haul, 10-12 MPG is probably good. On the other hand, we took the truck on a trip in November w/o a load (just passengers) and the MPG was 18+ hand calculated with the tank topped. So for this size rig, I was pleased and do feel the rollback helped MPG wise....just not when hauling loads. And it does appear to have better response at the lower end of the RPM scale.
I will offer this....I've been pleased with PHP and more specifically Bill. When he and I chatted on the phone for the programming, it's clear that he is a brilliant and good/solid person. I don't feel like he sold me anything I didn't need/want and I would trust his judgement. Bill and I talked at length about the programming and because I'm stock (no studs, etc) I was nervous about adding any more HP that could cause issues down the road. Although Atlas 40 may have been an option for me, Bill didn't push more and was fully supportive of my intentions while being on the conservative side.
So that said....if you can get a hold of Bill (he's incredibly busy and hard to catch up with), then suggest you chat with him and get his take on your situation.
