No... the 2008 4.3 v6 engine is not supported at all... never has been... only the v8's are supported...

not sure where you're looking, but there is only 1 model/version Predator X - https://www.diablosport.com/products/pr ... rts/DS-MFD

You can also get the better inTune i3 8246 Platinum - can get custom tuning done for it, etc... https://www.diablosport.com/products/in ... parts/8246

I wouldn't worry about it.... those Predator 2's have been discontinued for a while now, so are no longer sold/supported anyway... i.e. - there aren't any more updates for it, will not be any new updates for it, etc....

No... to be able to install a tune to the suburban in order to adjust the tire size, you will have to buy another GM license...

Mike, he's in Sweden....

none of the programmers can make it sound like it has a cam, aka a "ghost cam"... and besides, It's not good for the engine to make it intentionally miss and skip to sound like a cam...

you want a cam sound/lope, install a cam...

Nope... you want the loping sound, get a cam...

yes you can use e85 on the Diablo Tune... but only if your truck is a factory flex-fuel vehicle...

It worked. Thanks a lot.
Now. Is it possible to get a custom tune to the car?

I have longtube headers, open air filter, race catalyst on it.
What is recommended and how do I go about forward
Thanks again


I can definitely get you hooked up with a custom tune for your Camaro... I've done a ...

Not sure where I got Mustang from, sorry about that!

Load the attached file to the root of the i3 drive and let it import the file.

Then go to the car and select the tune menu and let it load this and it will set the pcm back to stock. It may ask us to repeat this for the TCM if it is tuned as ...

That's an issue with Diablo's server being down.. it can't connect to their server to get the files.. nothing you can do until they're back in the office and get their server rebooted...

You can shoot them an email to let them know at: [email protected] and/or [email protected]

you won't be able to do anything until you get Diablosport's unlocked PCM...
