Fuel Economy

Reviewed By Howard M (ENTERPRISE, AL) Reviewed for a 2005 GMC Sierra —12/13/2013 6:07 AM

I purchased the Bully Dog to increase fuel economy on my 6.6 GMC diesel. At first it didn't seem to make any difference so I called their tech support (they were great!) and discovered I did not have the settings correct. Since then I have seen an improvement on mileage and I love the different feel in the over all performance. I am glad I made the purchase!

Economind w/ IQ proves solid towing with my 2005 GMC LLY Diesel

Reviewed By Aaron A (Miles City, MT) Reviewed for a 2005 GMC Sierra —6/24/2012 2:23 PM

I frequently tow an 11k fifth wheel camper during the summer months. My previous tuner was the DiabloSport Predator set @ 40hp, note I have an aftermarket intake and exhaust. After towing with my new Economind/IQ setup for several thousand miles I can honestly say I've experienced noticable improvements. The best has been with observed fuel economy...when set at level 2 on the Banks system I have seen a consistent 1-2mpg increase in towing mileage (was 9-10mpg now 11-12.5mpg hand-calculated). I recently pulled in a hot, heavy crosswind and still achieved 10.5mpg! I have noticed that the DIC mileage display is quite accurate now as well, and I find that handy. Power delivery with the Banks is smoother than my old tuner and w/ much less smoke. The IQ display has really enhanced my towing experience, too. I can track digital engine temp more accurately than with the stock analog gauge. In OD going up a large hill I see about 16lbs boost, and EGT no higher than 1150deg. Downshifting produces up to 26lbs boost with similar EGT readings. Engine temp varys from 184-215deg and the engine fan cycles much less now. It's comforting to know how safe this tuner is when towing in hot & hilly conditions. Banks produced a quality product with the Economind and yes I would recommend it to others.
