Notes:
  • Tuners are a unique electronic device and, therefore, have a unique return process. This process necessitates physical inspection of the unit before a refund can be issued. Why? Because once a tuner is purchased and paired with a vehicle, it can only be used on that specific vehicle. This is called “vin-locking,” and prevents multiple uses of the product on different vehicles without license from the manufacturer. When returning a tuner, the tuner must first program the vehicle back to stock-mode so that it’s no longer locked to that specific vehicle. At this point, the vehicle loses the performance tune. If the tuner is returned while the vehicle still has the tune programmed to it, it will fail inspection as it cannot program another vehicle and is not in resell condition. The return will then be rejected with no return credit issued.
  • Features manipulated by this product may vary by application.
Moss Warranty Act Statement

Thanks to the Magnuson Moss Warranty Act: US Code – Title 15, Chapter 50, Sections 2301-2312, your vehicle’s factory warranty is protected by law when you add aftermarket parts.

great product

I did have an edge programmer before that worked but started having issues with it. Now that I switched I am very happy. I mostly do what I can for economy and this product has helped. I get almost 23 mph on highway that's more than I get with the edge. I did try the other modes and they did hurt mileage but it did open up the truck. I'm very satisfied with this tuner, might get the trinity some time in the future.

It was so much easier to use,understand and load the Diablo 91 P

It looks great,small and easy to handle, it's easy to understand and use. I used it to read and reset CEL Trouble Codes. Then I install the updates and repair Files,that was easy to do. Then I installed the 91 Protune and it was fast and also easy. After all said and down I did notice a much smoother running and idling car. I also noticed a less hesitant pickup and go. Car might not have gained 100hp but that extra hp the CARB Legal Diablo tuner installed is good

Chevy 2500 6.0

The P2 tuner was easy to install and the increase in hp was noticable right away at 87 Input setting. I also reset the tire size to get the odometer set right. After setting the programm and completing the set up, I went back in to set the odometer tire size and it wanted to completely redo the program again. So keep in mind that everytime you add or change the program, it will create a new program/folder. so reload your chosen options each time so they are grouped together. Very satisfied!

Great tuner.

This is a great little device that I purchased primarily to turn off the AFM on my 2008 Suburban. It did that with ease, and my vehicle actually runs smoother to boot. I only wish I had bought it sooner.

When all else fails read the directions

When all else fails read the directions. I purchased this Diablo tuner to tune a 2010 Jeep JK Wrangler Unlimited. I plugged in the tuner and when I was done the speedometer did not work however it was not the fault of the Diablo so I reinstalled correctly to change the tire size to 33.5 and gave it 2.5 inch lift I was able to adjust the speedometer speed and gave it the 87 octane tune to give it a little more pep without costing too much money at the gas pump.

Not much gained for the price

Easy install, did get some power out of it. But not enough to justify cost? Fuel mileage is the same haven't towed with it yet. Save up buy a blower!

2004 silverado 5.3

I was extremely impressed by the differance this tuner made on the drivability and overall power of my 2004 Chevy Silverado Z71 5.3 with 120,xxx. I had already installed a k&n cold air intake, flowmaster exhaust, and a poweraid throttle body spacer and was averaging 13 mpg city and 18 mpg on the highway but with the diablo sport tuner installed on the 91 octane tune im now averaging 17 in the city and 23 on the highway! Its rediculous to say the least. I recomend this product to every one I know. With gains like this why wouldnt you have one???

Definitely like the HP increase on the 87 octane tune. Haven't tried the 93 octane tune yet. I have seen an increase in MPG's but haven't ran a whole tank through yet to have an accurate MPG gain.

awesome product when used with a custom tune

great tuner bought it for my 99 silverado, had put headers on no cats, cold air intake and throttle body spacer, and dynomax exhaust, tried both the 87 octane tune and diablo tune, didn't work the best but then was able to have a tune customized for my truck, really brought my truck alive, never downshifts up a hill 0-60 no problem, all around runs stronger. a custom tune might run 100 bucks or so but tons of things you can play with and adjust on predator. great tuner and is well worth the money.

Diablo Predator

The device was easy to connect and the preloaded tunes were easy to install. Overall, I think the device is very useable. The documentation leaves a lot to be desired. It does not give me enough informatin to utilize the device like it could be.I would like to see a more detailed instruction book that would instruct me on how to utilize the many functions of the device. I would also like to see an unabreviated list of all of the functions and what they do. I am a new to the use of a tuner and do not have the back ground of many people that may already be familiar with the terms utilized on the predator and would rather not make a guess as to what they mean and what they do. I bought the predator for an increase in fuel mileage but also wanted better performance. It appears that the performance is there but I am not sure of any increase in fuel mileage. The transmission also shifts out better.

Ease and performance

It was very easy to install and I am very satisfied with the difference that I have noticed in performance and increased miles per gallon. I drive a 2006 GMC, 2500 HD, crew cab, with Duramax 6.6liter and am getting about 10% better MPH.

2006 Dodge Ram 1500 Mega Cab Hemi

Predator worked great with the other performance mods I did. I put a custom 3" exhaust w/ a dynomax muffler, the Predator, a throttle body spacer(JET) and a Spectre cold air intake. The combo really woke up my truck! At a rolling start doing approx 15-20mph... if I stomp on it, it will spin the tires effortlessly. It pulls on my friends 08' GMC 1500 Denali pickup w/ the 6.2L, and he has exhaust and a K&N intake. The gas mileage is about the same as stock but it has a very noticable power increase. I'm using the 87 performace setting. I haven't tried the others yet.
