Good tuner?
Bought this specifically to adjust my gear ratio for my tires, but because I don’t have a Rubicon, that feature doesn’t exist. As an engine tuner it works great.

Not impressed
I've been trying to get the tuner to load a tune into my 02 TJ for over 2 weeks only to have an error message saying there is no tune in the tuner. The computer says it's loaded and ready to go but no tune is found when plugged into the Jeep. Called Diablosport and had they got their engineers on it, told me it was fixed only to have same issues. Even with different tuner same software problem. I got so frustrated with it I sent it back.

Diablo Predator 2 tuner - great! Product did what was advertised. Fantastic pedal improvement, speedo recalibrated for bigger than stock Coopers and big assist climbing Colorado hills on highway. EZ install. Would recommend for any JP.

2006 Rubicon Unlimited - Joshtur
Noticeable
Installed on my 2006 tj 4.0. With a cai and cat back exhaust my still was pretty sluggish, after the Diablo install and on the 87 performance tune the gains were noticeable. No more struggling to make it up steep hills.

2006 Rubicon - Johnstone
Not what you need if you have a manual trans!!
I have a 06 rubicon with manual trans. This tuner will not correct the speedometer or let you use lockers in high range. But its a nice power adder.

Great Product!
Product is great for the inexperienced tuner, very easy to use with a very clear and bright touchscreen. On the road i got roughly 2 MPG better, and off the road it definitely gave a noticeable boost! Overall love the product for my DD/Toy! I'd definitely recommend!

2013 Wrangler - Slickster
Wifi updates no need for PC
Received my Diablosport I3 in a timely manner. When ordering two are available with or without wifi for the same price in the description. The Wifi was an important feature for me because I do not own a PC/Laptop. On arrival and unpacking I noted care was necessary while handling the Diablosport, I wouldn't want to test the impact resistance. First thing was first, I went to settings and the wifi menu option and connected my internet, updated, then plugged into my 2013 Jeep JKU. The Diablsport updated the PCM but after selecting a tune stated no calibration was available for my Jeep and to connect to a PC. I was relieved to discover simply going to the advanced menu option and selecting an update was sufficient, the Diablosprt downloaded a calibration file for my Jeep. I selected the 91 tune, and then after calibration changed tire size. Impressions? Night and day throttle response improvement, more responsive, and shift points were not early. No buyer's remorse here! I was worried about not having the option to firm up the shifting for my auto trans but seemingly Diablosport had that covered. The stock smooth, flat up shifting added anxiety as I wondered about the longevity of unnecessary clutch pack slippage, but again the overall Diablosport package was an adequate calibration.
