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.

Lose the lug! MANUAL TRANSMISSION 2015 Colorado WT

Reviewed By jared b (WEST LAKE HILLS, TX) Reviewed for a 2015 Chevy Colorado —8/20/2016 9:08 AM

So this is my first upgrade experience with vehicles. I recently installed a CAI, which was great, although louder than expected. I gained very noticable HP from the CAI and was expecting the same from this chip, if not more, however, i didnt see the 25+ gains quoted. What I did notice was,yes, more HP, but more importantly, the chip just smoothes everything out. Throttle response is instant and metered, and when at low rev, for example, it blasts thru that rev point where it would normally lag
