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.

2015 Toyota Tundra 5.7L

Awesome product!!! Great step by step instructions. Had 0 problems with the installation, it took about 45 minutes from start to finish. I would recommend you measure your tire to get the exact size. I upgraded to a 22in wheel with 35s and programmed 35s first and it was still off 2 MPH. Once I measured and saw that it was really a 34, I programmed that in and it was perfect. Much smoother shifting too. I also noticed a 2mpg gain too!!! This is a must if you have a lift Tundra with 35s or larger
