GT on 2004 F250

Reviewed By John S (BOWDON, GA) Reviewed for a 2004 Ford F-250 —4/17/2016 10:21 AM

Easy to install and like the look. The biggest reason I settled on it was the shift on the fly ability. I do a lot of towing and a lot of highway so this makes the transition much easier. Noticed a huge power gain coupled with my modifications.

Bully Dog GT Tuner valuable addition for Ford F-250 towing

Reviewed By Warren H (Apex, NC) Reviewed for a 2002 Ford F-250 —11/7/2015 9:10 AM

Bully Dog GT Tuner added to 2002 Ford F-250 7.3 diesel for additional horse power and torque to tow a 12000 lb 5th wheel camper. Tuner has performed as promised to provide extra towing power - especially valuable for towing in the mountains. Just as valuable is a gain in fuel mileage of approximately 3-5 mpg whether towing or not. Also important is ability to view specific vehicle performance parameters: most recently transmission overheating. This prompted addition of an extra trans cooler.

Reviewed By Jeffrey B (Santa Claus, IN) Reviewed for a 2009 Ford F-250 —6/19/2015 7:51 AM

I have had nothing but problems with this tuner always showing a P0088 code. Fuel rail pressure high have talked to bullydog 7 times still not fixed. I would not buy another one.
