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.

Good product!

Reviewed By Lawerance W (Vineland, NJ) —2/20/2015 6:39 AM

This performance chip definitely increased the horsepower by pretty noticeable amount. It's not going to do anything for mpg so don't get it for that reason. My 0-60 went from a stock 8 seconds to 6.7. I definitely recommend it.
