In addition, the GT line features all of the same gauge/monitoring functions as well as the advanced driving coach software aiding drivers in maximizing their fuel economy.
this tuner was easy to use and quick to learn with. based on the intake system and cat back exhuast i had on my 2014 silverado before doing this tuner i can say that it helped make those upgrades shine just that much more. i noticed with all three upgrades done that i was averaging between 20 to 23.5 miles per gallon as seen on the driver info screen on the dash. my only hiccup with this system is that routing to power wire for the ignition switch is a bit tricky but worth it so you dont have to keep turning th unit on and off again. other wise i would by this all over agian if needed.

I should have done a little more research on the product. Unfortunately I was unable to adjust tire size, that's why I bought it, to help with shift point. Wasn't able to do so. Other than that I would definitely recommend this product to anyone out their who wants to make a little extra power.

Triple Dog Gt Gas
Purchased the Gt Gas looking for some improved performance as well as MPG increase. Having run a Bully Dog programmer on my diesel truck in the past i had an idea of what to expect but was new to tuning Gas applications.
All i can say is wow! In my 2013 F150 with the 5.0L engine i definitely noticed a big difference. The throttle response and power had a great improvement but where i was very excited was the mileage. I was averaging anywhere from 14-16 mixed driving. After tuning my 5.0 in the performance setting i was getting anywhere from 17-19 mpgs hand calculated!
The driving coach was slightly off at first but a quick call into Bully Dogs Technical Support had me fixed and %100 accurate in a very short time.
The Gt Tuner was well worth the money. I will be back to Bully Dog for more products in the future!

I purchased this product about 5 months ago and the HDMI port on the back of the head unit broke off. There was also a foul burning smell coming from part of the product. I sent it back to Bully Dog for replacement. This product is JUNK and could have destroyed my computer in my truck. I mainly purchased it to increase my HP and improve my fuel economy. It did a good job increasing HP but did nothing for the fuel economy. My MPG stayed the same as it was and even decreased and got worse once this product was installed. This product is a waste of money. It really doesn't do everything they say it does. Bottom line: it's junk and I would recommend saving your money and not wasting it on this garbage.

HP but no mileage improvement
I installed this on my 2002 gmc 2500hd 8.1. The only upgrade that i have is a 3 and 1/2 exhaust. I had this product for about 3 and 1/2 weeks. Right away I could see the performance no problem lighting up the tires. Ran two tanks of gas on performance mode at 91 and went from 10.5 to 6.5. Also tried regular mode with 87 the best I could get 9.5. The mpg doesn't calculate correctly. I returned it and just going to install cold air intake and throttle body spacer.

great product...but fuel saver mode does nothing but limit the throttle response. i got better mpg in performance mode due to the fact i could get to speed in a timely fashion and hold speed at a lower rpm.

Don't do it
As soon as I installed this unit I experienced nothing but trouble.. from horrible gas mileage to my spark plugs and wires all of a sudden going bad, reduced horse power dramatically, my trucks computer even said reduced engine power while the unit was downloading not reccomended at all.

INCREASED HP NOT MPG
Helped on my 03 Silverado 5.3 on HP and shift firmness, but didn't see a difference in fuel milage. It doesn't interface well with Bose stero systems either, but Bullydog Support helped me get it working. It was a bit expensive though and doesn't look great in the cab.

if you're looking to increase you gas mileage then keep looking because this will do nothing or worsen it. bought the GT yesterday for my 06 nissan titan 4x4, installed it, set it to the fuel saver mode and and was driving as conservative as i possibly could to satisfy the driving coach which only gave me a c+ having my truck on cruise control most of the time. i drove about 50 miles most of it highway and my mileage went down 2mpg. so not only was it a lot less fun to drive because i needed to accelerate super slow i also lost 2mpg. total waste of money! easy to say i returned it first thing this morning. 4 wheel parts in thousand oaks on the other hand provided outstanding customer service and refunded my money immediately! all the associates are very knowledgeable and helpful. will definitely be returning! Bully Dog has most certainly lost my business though!!!
