So i just got my 03 f250 back from the dealer because i broke the shaft in the turbo. It runs a lot better but i just got an SCT X3 and when i run it on performance it is almost like it is defueling but it sounds like the turbo is cutting out. The only way i can describe is it its like the truck is cutting out and i was thinking it might be the pump and actually is defueling. I hooked up the SCT and it didnt read any DTC's. Just wondering if anyone else has had a problem like this or if anyone has ne clue what this could be. Your hellp would be greatly appreciated. Thanks

If you don't have custom tunes, get custom tunes. If you do have custom tunes, get new custom tunes.

So i got my custom tunes on my truck today and it still cut's out when its on a certain tune. sounds almost like it could be an injector pump but im no diesel tech. And another thing i bought this tuner off someone whos had it on two trucks and this will make the 3rd one but still says 5/6 unlocks left is there something i have to do to it so it knows its going on my truck

my 7.3 did that and all we did is get a map fooler, after that the beast would spool with out cutting out. my 6.0 just died before i could tune it so it might be different on it
