Mo Go - but a little more fuel cost

Reviewed By Thomas M (Carbondale, CO) Reviewed for a 2001 GMC C/K 3500 —7/2/2010 8:18 AM

Slam dunk to install. Had to remove 2 fuses but down loaded with no problems. Tuned to "regular" gas in an 8.1 GMC and had some ping but called in and the regular setting is set for 87 octane and I had 85 so bought some octane booster and solved that problem. Later fueled with 1/2 premium and 1/2 85 and so far no problems. Power gain is noticable, especially in mid range. A little dissapointed in the 87 octane setting as I was after performance gain as well as cost and ended up costing about a dime more per gallon for the 87. Haven't run enought to notice any fuel milage gain at this point and it is hard to keep your foot away from the firewall so we'll see if the additional performance is worth a dime/gallon. At this point I would recommend the programmer, however.

Tuner works fine

Reviewed By Keith B (New Berlin, WI) Reviewed for a 2008 GMC Yukon —9/4/2015 5:07 PM

The tuner works fine on my 5.3L GMC, but I was unable to get the Software to work, even after contacting Edge the maker of this product. I really only wanted to be able to disable the Active Fuel Management, but this unit does so much more.

Gives my 3.7 V6 Ford attitude

Reviewed By David M (GREENWOOD, AR) Reviewed for a 2011 Ford F-150 —10/1/2015 10:54 AM

Tuner # 1842 made truck respond like V-8. "Told" tuner that I had different gears to make up for tire size and worked perfectly. It changed dramatically the shift points and acceleration. Love the perf. tune. I think its the best "canned" tune available. 37hp increase on my 3.7 L
