I can definitely get you hooked up with a custom tune for your truck..

Any mods done to it?

With the custom tune, you'll gain even better/quicker throttle response & acceleration, stronger/harder pull, smoother & quicker power delivery throughout the rpm's, better tranny performance/shifting (for automatics), etc...

I change a lot of things... a small sample of just SOME of the things are: disable torque management, adjust part-throttle fueling/timing, WOT fueling/timing, knock retard settings, throttle settings, tranny torque, tranny torque management, tranny shifting settings (for automatics - pressure/firmness, shift points, quickness), etc...

So i have to pay another 150$ on top of the $300+ That the intune cost for a custom tune for my vehicle i can get a professional custom tune for 200-300....i think ill just throw this pos back in the box box and get my money back

yes custom tuning costs a few bucks... Diablosport themselves does not do custom tuning for the public.. This is my own business, being a Diablosport CMR custom tuner/dealer, so yes it costs money for custom tuning, from ANY custom tuner/dealer... nobody works for free..wouldn't be in business long if that were the case haha..

If you don't want a custom tune, you don't have to buy one.. you can by all means just use the tool yourself with just the adjustments that it has available on it...

Have a good day.
