Installation Time: Full Day
It's okay
The Hemi Ram with the six speed auto shifts hard into drive and reverse on regular tune. Haven't tried the higher tune yet. Stock tune is really smooth. Might take a while to install due to communications with live support. I think it is still worth it for the gauges, DTC codes, and multiple other things you can do with this tuner.

I love the GT tuner. I purchased one for my 2012 dodge ram and it's definitely a big difference. I recommend purchasing one for any pickup.

It work ok
Because the power wire is a pain to run through the fire wall on the dodges I'm not returning it. I'm a mechanic doing a build on my truck outside of work. I researched everything and thought this would let you turn off the AFM system it DOESN'T so save your money. I'm going to pull the engine apart and remove it completely that way. I'll use this for right now and find something better and resell this to one of my guys.

2012 ST -
Amazing
I didn’t think much of the fact the Bully Dog could control throttle response so easily. Was I ever wrong this is like driving a supped up wildcat now I had to turn it down to get use to the immediate response time of barely pressing the foot pedal. Highly recommend for anyone wanting immediate response from pushing on the gas pedal!

Just so you know, this is not one of those "buy this and everything is perfect". This my friend is a part of a system which will require the proper support, whether it's upgraded Bolt-ons or change of fuel. I will say that with the proper combination of parts,etc,....this is worth it. Put it this way,....without the proper supported parts, your gonna see cel for days or anytime you get on it. It's worth it!

Bully Dog Tuner - F250 6.2L
My truck has some mods, larger wheels and tires that required some adjustments to the truck. I used to have a the Flashpaq for my F150 but SuperChips doesn't alhave anything for the 22 F250 with the gas 6 2. Called American Trucks and spoke to Nicholas. He checked found a couple of options and made a recommendation based on my needs. It was the Bully Dog BDX. Install was a breeze. I've used a similar product in the past so I was somewhat familiar. The Bully Dog was similar but the best part was that it connects and updates through WIFI. No need to download the updated unless you are going to install a custom tune. There is only 1 tune available for my model currently. I'm hoping additional setups are added in the future. Great job and big thanks to Nicholas for finding what I needed, and placing the order while I was in the phone.

Bully Dog Tunner
2017 F150 3.5 Ecoboost 4wd, 10sp, 96,000 miles. Truck is 2’ leveled, has 33x10.5 tires, 4” MBRP cat back and drop in K&N filter. Big difference in power when you get into the throttle. Truck will light tires 1st, 2nd and chirp into 3rd gear. 4wd launch will put you in the seat. Not a huge difference when driving truck easily, but did notice much better throttle response and an increase in MPGs when driving easy. Would recommend to anyone looking to squeeze more power for a fairly cheap price.
