Any hope for a 5.3???
:bang: 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!!!

Nope, the 5.3L sucks. Yank it out and throw a 6.0 in there :eyes:
Ok, just kidding. It's your tuner, fire it. |
What gear do you have? Keep in mind that even on the stock tires, they are almost 32 inches tall, and you have a heavy truck.
|
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.
|
Like Zippy suggested a decent torque converter will get you in the powerband, that with a good tune will get your tires smoking.
btw I was kidding, my Z71 has a 5.3L :nod: |
time to start searching this forum. dont spend another dime until you search the heck out this place. 5.3 are plenty powerful if setup right. what are you tring to accomplish with the truck? BTW welcome to the site.

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. |
