Rated 4 stars only because I had some trouble tuning my vehicle and called Diablo twice first time was on hold for 50 min and second time someone answered after 55 min and told me everyone had went home for the day they took my name and number and said someone would be getting into contact with me the next day they never did so good luck if you have any trouble I figured it out myself .
So I decided to get corsa catbac exhaust and all the reviews were saying to get this afm disabler to prevent any kind of drone issues. I was also tired of the constant back and forth in town with 4 and 8 cylinders. Wanted something to solve both issues. Well this was it. Probably the easiest install ever. Just plug in and go. No more v4. It's fantastic. Works as described. Best part is no codes and no warranty issues. small blue light but I don't mind it at all. Best price here and great product
2011 F150 5.0 Bully Dog GT Tuner
I've had Ford diesels since 99, so a tuner on a gasser is no where close to the value of a diesel tuner, but my truck has a 6" lift with 35's and stock 3.55s.The truck would only hold 6th gear from 68-70 MPH, so I got a tuner in hopes that a few more HP would be enough to hold it in gear so I could use cruise control on the highway. It did, and also my MPG has gone from 13.2 to 15.1 in the past 3 tanks of gas. The extra HP is noticeable, and I was able to adjust the speedometer for bigger tires
