Any hope for a 5.3???
Ok, I have a cold air, an exhaust and just put the Diablo Predator on my "04 Z71. I still can't even hint at a tire scratch when I take off. I turned the TM off and still nothing. It doesn't feel any stronger than stock. Am I missing something in the programming or could I have a real problem with something else, or are these motors really just that weak??? Somebody help, please!!!

At only 325 cubic inches you need a converter in there to really turn the tires much unless you are using the brakes. As for tuning, if your device is a handheld it's not really tuning, it's wishing.

Lol. If I had the time and the money I would just sell it and go back to a diesel, but I don't so I gotta settle with the 5;3 for now. I have 3.73 gears. I know its heavy and all, but I can't believe its so gutless below 3000rpm. It runs good after that.

EDIT: You might also want to use the diagnostic feature on the predator to view real time data while you drive your truck and make sure you aren't getting knock retard or some other issue.

Something must have been wrong there to loose power. On Monday I was running my factory tune and there was a huge diffence from the tune I have with the predator. Just installing the canned diablo predator performance tune doesn't do much, but you can modify the canned performace tune or get Diablosports to do it for you. It also has a feature to view real time data so you can monitor (LTFT and KR) for instance and make necessary adjustments.
