Just wondering what settings anybody is using with the tune on the Predator. I've only changed the top speed and the tire size and installed the tune.

 

to tell you the truth if you contact Diablo and talk with one of their techs he can line you out on a custom tune. They have a program on their site you can download to upload your tune and download a custom tune. Just let him know what you want to get out of your truck. The tune wont be as good as a dyno tuned PCM but it will be alot better than the so called performane tune that comes on the predator.

 

Well I talked to our local dyno guy and he said that with the only mods that I have a dyno tune would be all that I need right now.

 

thats cool I just know Diablo done up 2 custom tunes for me for free when I had mine.

 

Free?? ummm what did you tell them when you talked to them.

 

I emailed this guy johan@diablosport.com and told him what I wanted and this was his reply
You can go to the downloads section on our website and get the 1999-02 gm pc interface software and instructions and you have to follow those instructions and then e-mail me the tune.
after doing that I was on my way to a free custom tune.

 

Thanks, i think ill send him an email and see what he can do.

 

So you didnt have to pat the 1 time tuning fee?

 

they never charged me a dime, look into it and see what happens.

 

Maybe I can luck up!! thanks.
