    Predator 2 for GM Diesel Truck is rated 4.4 out of 5 by 8.
    Rated 5 out of 5 by from Duramax 6.6 Experiment I bought the Diesel tuner version about a month ago. I recently got my first diesel (2011 Silverado 2500HD Duramax 6.6) and though it runs well, I knew it could do better. I shopped reviews of all the reputable tuners and decided on the Predator 2. Tune 1- Economy: Didn't notice any real difference other than the shifting seemed better. I adjusted for 33.50 tires. I kind of baby my vehicles and that may not be the best for a diesel. Tune 2 - Performance: Felt lighter and more responsive right out of the driveway! I could feel the power under the hood. Like I said, I baby my vehicles but this made me curious what the truck can do. Took an on ramp to the local highway, got it up to about 50mph and let 'er go. Rear wheels broke loose, the box shifted slightly and the truck took off like a scared rabbit! Seriously, accelerated like a beast! At that point I could care less about fuel economy, lol! Tune 3 - Tow Performance: trailered the tag-along toy hauler, loaded with two big touring bikes and all the camping and riding gear for two adults to Daytona Beach, FLA (apx 1200 mi). Truck ran effortlessly for the whole trip, including the nasty little hills in V & WV! Had trailered before without the tune, so it was a good opportunity to see the value of a tuner - if any. Tune 4 - Stock Tune with tire adjust: This was the real test - both for the Predator 2 and my patience. I wanted to drive back from Florida on the same roads home, a mirror drive of the way there with no real optional tuning. I found the truck ran like a good diesel, but felt sluggish with a little more noise under the hood when passing or going through the mountains compared to Tune 3. ** Here's the kicker: Same miles on both trips and $30 less in fuel with the Performance Tow tune. Truck ran much better with this tune and was cheaper. Even if it was the same fuel amount, I wouldn't care - the Predator 2 proved itself well worth the price. Tune 5 - Economy with tire adjust: Back home, normal daily driving. Shifts better than stock and seems to have a bit more launch. Too early to tell if there's any real fuel savings. Doesn't seem as important now that the truck seems to be a better drive under all conditions. Very satisfied with the Predator 2 and I highly recommended for this Truck! Drives like it should! Ordered it from Diablosport and I had in my hands in three days!

    Rated 5 out of 5 by from Does exactly what it's made to do Took my factory 3500hd Silverado WT SRW Duramax Allison from being a field burrow and turned it into a full on Stallion Stud. Awesome horse power gains. Incredible torque gains. And it eliminated that nasty speed limiter. GREAT product!!! What you're going to loose. Cruise control and fuel economy. Which I can deal with the fuel economy. But my cruise control? Come on guys. It'd be nice to be the bad ace diesel and still use my cruise at 75 mph here in Texas. Other than that, awesome product!

    Rated 5 out of 5 by from First time tuning Easy to use, instructions complete. The economy tune does not appear to make a difference in fuel consumption, that could mean there is something else wrong with the truck . The right tools at the right time to help me identify the true cause. I really like the tool as it has a code reader as well and it allows you to tune.. your tune... Based on tire size, etc... Very happy with it as it opens up other options with my towing.

    Rated 4 out of 5 by from Works well as past units I’ve purchased but... Easy of use and features are both great but I don’t understand why the top speed value can’t be raised without disabling the cruise control??

    Rated 4 out of 5 by from Good product I bought this and it works exactly as it's supposed to. Unfortunately it doesn't do what I thought it did or want it to do which is delete. Wish I could sent back and purchase the correct one.

    Rated 2 out of 5 by from preditor 2 i had a diablo tuner years back it was good with my 2003 gmc duromax. the new tuners do not work well without pulling a lot of fuses on 2001 to2007. diablo is a good product but that is not mentioned in product description.

    Rated 5 out of 5 by from Diablo Sport Predator Easy to use. It increased the performance (smiles per gallon) and fuel mileage 2-3 mpg on our Duramax, if you can keep your foot off the throttle!!! It begs you to stomp on it.

    I have a 2004.5 LLY duramax with the transmission converter to a 6 speed. How will it effect the shifting on that? Is there an option to not touch the Tcm tuning?
