Diablo Predator Programmer

bdog2002 · July 23, 2003

I installed the predator today and man, do I feel a great diffrence. The truck is strong and no problems. Shifts good and runs hard with no hesitation. I am very glad with the performance of the programmer. Great customer service. The thing that gets me is how fast the response is, when I lightly press on the gas it takes off. Great product. Make driving fun. Before my truck would bog down when I reached 95mph but now truck just wants to keep going. The beast of my 5.3 is alive, kicking and very aggresive. Just got to make sure the beast does not try to control me.

Did you use the stock tune, or have a custom one made?

1BADHD · July 23, 2003

I have finely fine tuned. I am barking the tires on the 1-2 shift. With my 35's! Wonder how long the 4L80E will last like this?

BDBWTE · July 23, 2003

Yep I'd be waiting for that 4L80E to make a wrong noise then start pu$$y footing it. Those Auto's don't like spirited driving.

I used the tune that came with the programmer. I have not gotten to messing with the settings, as you can adjust alot of things with the diablo. To tell the truth I do not even know how to go about adjusting all. Any help from some fellow diablo owners. All I can say is man the tune that it came with is awsome. It amazes me that you can still add on to the tune that the programmer comes with. I am happy, I have heard alot of hype about the westers. I am pretty sure it is awsome as well, but the options ths programmer gives you is great. Plus you can always restore the stock tune and not worry about the dealer trying to blame you for tinking around. Kinda sad, you pay hard earn money just to have the dealer tell you no no, don't touch! Anyways any help would be greatly appreciated. Thanks

Autos with faster shifts usually last longer in my experience. It is the joints that fail.

I paid extra for a HD tranny. I am going to use it.

And yeah, since the shift is faster, there is less slippage. Therefore, usually lasts longer.

Hey 1badhd is it wise for me to do these mods you described. If so what will I gain. I am asumming a hard shift. If not just that explain, if you have the time. Thanks anyways I really appreciate it.

opps sorry messed up, could not erase duh. Anyways 1BADHD

I have 02 silverado ext, 5.3, 3.73 with locking diff, tow package, trans cooler

Ok, what that basically does is makes your tranny shift firmer and much crisper. The shift rpms and mph are to keep you in your powerband while shifting. Make the changes if you dont like them, it only takes a couple pushes of a button and your back to the stock tune.
