DiabloSport 7102 Predator 2

I ordered the CARB Approved unit (wanting to be legal here) knowing that I'd probably have very limited canned tunes and probably less individual adjustments. I was happy to see three tunes pop up. I went through the easy steps (seriously, a chimp can use this thing), and ended up loading the "87 Octane Performance Tune". My guess is, being CA, there was no 89, 91, or 93 octane tunes available. The other two tunes were "tow" and an MPG tune. I then adjusted the tire size to my new 32's, and also, confirmed the rear end was 4.10 gearing. I needed to fix the speedo. Then I firmed up the shift pressure a couple notches. Well, lemme tell you, I noticed a difference in acceleration right off the bat. Now that I've put almost 200 miles on it, it's like a brand new truck. Takes much less gas pedal to get up our canyon hills here, it hangs onto gears longer with less foot, and it's NEVER pulled this hard, WOT. For around 350.00 delivered, it's worth every penny.

Worth every penny! I was skeptical but I finally talked myself into this purchase. I'm so happy I did. It made a huge difference in my 2003 F150. I have replaced parts for the past 2 years that made little to no difference in performance, but this did the trick. 1000% much better running truck. Highly recommend.

On my 2013 F150 3.5 Ecoboost, I only wanted to remove the speed governor, and this did it. Couldn't tell any difference in performance, but I used the Diablo tuner right away after purchasing the truck.

It was good. Needed more though

I have a 2001 Ford excursion 5.4 LI did a lot of research to get the best TunnerI even called to verify this will work and turns out they were just trying to make a saleI don’t recommend this product not only was it expensive, but it did not work

I would try taking truck to a tuner, tell them what you want.

Bought it for my 2003 F250 5.4l has engine. I was really impressed with the gains it produced, I would definitely recommend this tuner to anyone. This is my second Diablo tuner for my second vehicle. I love it!!!!!

This unit is the same as the Accel Tuner…. It was listed as compatible with my vehicle but was not…. I received the above message but never received any word from the manufacturer afterward! Also still waiting for my refund!
