Awesome product. Great power gains. Only complaint is I can't reprogram back to factory but who would want too.
Ruff idle
Josh Shelby (United States) 8/10/2011 12:05 AM
Seems as though every where i look i see ruff idle and diablo in the same sentence. I only wish i would have seen this before i bought one. After my purchase I noticed a ruff idle, injector rattle on decel and jerky cruise control down hills. Diablo told me it was due to added timing and couldnt be tuned out. I was advised by a fellow diesel tech the diablo was bad about eating injectors and electronics. A few months later i had a injector drop which i diag and replaced myself. Low and behold the ruff idle and clatter is still present with the diablo on any setting. I took it off and the engine runs fine. I installed it on a buds2006 dodge as well and his began the same issues. This friday i am replacing the diablo with a H&S. By the way i refuse to put it back on my truck. There is a reason its less than $300. STAY AWAY!!

I installed in my 06 mega cab and and my mileage is now between 24 and 25 mpg. Power is awesome even on economy mode and will smoke like crazy too. The only complaint I have is when its cold out the idling look loop is a little rough. Other than that its a great product for the money. Would recommend to anyone.

Big Bang for the Buck

Dodge 2500 Mega cab 4x4 cummins diesel. CFM intake, K&N cold air induction, 6 inch Bully Dog exhaust, and now Predator programmer. Easy to install and awesome power. Resets for tire size and I got 5 miles to gallon better. I would have never believed the milage increase. Went from 19 mpg to 24mpg on extreme. Great buy haven't floored it yet for fear that my stock tranny will give out from all the power.
Rough Idle
Dan (Northern California) 4/13/2010 1:15 PM
This programmed corrected my speedo and calibrated my tire size but made my truck idle really rough. I sent the Diablo back and I am going to order a Smarty Jr. this week. XDP was super friendly and helpful and took the Diablo back with no problems. That's why I will continue to order from them. 2006 Dodge Cummins 5.9, 6 inch lift, 35 inch tires, K&N cold air intake, 4 inch exhaust with cat delete.
Great Product... Great Bang For Your Buck

i bought this product bout 2 yrs ago. i love it, the power gains are out of this world.(and lots of black smoke too) i had it on an 07' dodge 2500 auto, ran it on the extreme setting... AWESOME!!! ran it for almost 2 yrs before the tourqe converter started to give. i sold that truck and now i put in on an 06' dodge 3500 6 speed, once again awesome power gains. on the 6 speed with stock clutch i recommend you not to go over the towing setting, the clutch wont like it. so i just upraded to a Valair 500hp single disc performance clutch, with air intake, and 5in exguast from turbo back, and a bully dog watch dog monitor. i can now run it on the RKL EXTREME setting.... once again power gains are outta this world. i love this product, i recommend it to anyone. great price, great power!!! thnks XDP

I bought this product so i could get better fuel economy and correct the speedo. What i ended up getting was out of this world, i have it set on the fuel economy mode and i still have a ton of power i am kind of sceptical to put it much higher. This is the easiest tuner i have ever used, basically if you can read and push a button you can work this tunner. I have a 2006 cummins and i get about 20 mpg, i do both city and highway driving. overall it is a fantasic piece of equipment and i can't wait to get and exhaust and an intake.
Lovin it

Great bang for the buck

I stacked a powerpuck and programmer. Set on extreme performance my clutch won't hold much more than half throtle. South Bend cluth will be my next purchase. This set up out performs the edge comp I had on my 98.5 ISB hands down.Beware, the powerpuck without the programmer was not impressive, you can barely tell it's there. I would recomend the proggramer, with or without the powerpuck this product is well worth the money.
cant be beat for the price...

I bought this unit in June 2008 this unit does have alot of power don't get me wrong. The problem is in our cold climate when the truck idles up it is a really rough looping idle. I called diablo and spoke to Mike the customer service manager and he told me that they knew of the problem but have no plans to fix it. They would not take it back because it was after the 30 day return policy well it is not cold in July. After talking to Mike and getting no where I called Robin at XDP and she resolved the problem for me and took the Diablo back and I purchased a Madds Smartty and there is no problem with this unit in the cold. I would really like to thank Robin for helping me out and I would never buy anything from Diablo again as they were not willing to take the unit back nor try to fix the problem. Mike says that it would be to expensive to send engineers and tuners to a cold climate and resolve the problem. I don't think that Diablo is very customer friendly and they don't care about that they have a problem with this just wanted my money and that was it. So if you live in a cold climate BEWARE.
more than a bang 4 you buck

I just installed the predator in my 07 Cummins 4x4 and man was I impressed. Very easy to program, took about 10 minutes. Amazing turbo spool, horsepower, and tons of black smoke. I highly recomend a gauge system though, so you don't tear anything up. But other than that, i'd already installed the AEM workhorse intake and custom 4in strait exhaust. Bottom line, great product, high gains, somewhat low price.
