Diablosport Forums

I just purchased a Predator for my 07 Ram Hemi and i was hoping someone can answer a few of my questions. I noticed alot of people talk about getting custom tunes from Diablo or from CMR. Do you usually have to pay for a custom tune or how does that work?

Also, if that was the case, will they make a tune for my truck with my minor mods, K&N CAI & Cat-Back Exhaust with 87 (89 or 91) octane?

custom tunes are purchased through cmr tuners like hemifevertuning, Green Racing, HHP, DTP, etc.

They can be made to accommodate any mods you have done or simply to improve perform,ace of a stock vehicle.


Thanks
