Soooo, I'm new to this sight but, I've had the rebel since July. It's the best truck I've ever owned BY FAR. Traded in a 2015 GMC Sierra slt with all the goodies for it. But, I've got a spare rebel Pcm that I've sent out to diablo to get unlocked. Im getting pretty anxious to get it installed. But, I'm wondering if anyone can give me any real world reviews on performance changes with the diablo trinity tuner. Any info would be great. Just put on a magnaflow muffler with the black tips. Didn't buy the complete kit because our trucks already have mandrel bent 2.25" tail pipes.

@ Tde0411 installed a Diablo sport trinity tuner, pcm, and oil catch can in their Rebel. You can read about it here: http://www.ramrebelforum.com/forum/ram-rebel-accessories-modifications/5209-rebel-mods.html

Awesome. I did get the ecm installed and the Diablosport 91 canned tune loaded. It made a noticeable difference but the hemi still seemed to be holding back its potential. I contacted Greene racing and Jay hooked me up with a custom tune and all I can say is WOW!!! It's a whole new animal. Completely different manners. When I put the pedal down the truck just rips. It'll even get rubber on the 3-4 shift under WOT. The way he tuned it is perfect. When I wanna cruise and just drive it seems calm but once I push the pedal past half it just comes alive. Pulls VERY HARD all the way to well over 100 mph. Just what the doctor ordered!!! Greene really knows what's up. He's very knowledgeable in these Hemi's and knows how to safely squeeze hidden HP out of them. Now the only problem is figuring out what mod to do next........

The second my Rebel is off warranty this will be on my Christmas list!

The way I did it (the recommended way) is to have a spare ecm. I found a used one in a salvage yard, sent it to Diablosport to have them unlock it and now it's installed for tuning. If there's ever a warranty issue needing service you can just install the original and take it in. The dealer can't tell you did anything. I wouldn't have done this if there were a chance I'd void the powertrain warranty. The difference a good tune makes is WAY MORE than any bolt on part.

I will keep that in mind!
