Tuner issues or?
I have been having this issue with my truck for some time now. Recently it has been doing it often enough to aggravate me which is why I finally decided to post about it. It happens when switching in between tunes on my DP tuner. Say I go from my tow tune to my economy or vise versa. The bottom end of the truck just goes away. I can put my foot to the floor and the truck acts like it's bone stock (or worse). It won't roll coal, doesn't build boost, just slowly climbs RPM until it reaches 2200-2300 RPM and then it takes off like a shot. Back when I first purchased the chip two years ago, this only happened every once in a while and I don't think it started immediately after install, which is why I am unsure if it is the tuner itself. Recently it seems to happen every time I change tunes. Any ideas?
