Solved that annoying back and forth shifting

Reviewed By Roger C (Wetumpka, AL) Reviewed for a 2011 GMC Sierra —12/25/2014 8:16 PM

I bought my truck used and knew nothing about the "economy" shift to 4 cylinders. My truck did it like crazy and I thought my transmission was broken. Did some research and found this product. Works as advertised. And I like it.

Reviewed By Clement W (Albuquerque, NM) Reviewed for a 2014 Chevy Camaro —12/25/2014 9:08 AM

I was VERY pleased with the price and speedy delivery of my new Programmer. The 91 Octane tune works perfectly and the elimination of the "Skip Shift" was an added bonus, The staff was able to answer all my questions prior to the purchase and made the decision easy. This is a great product and I like the fact that you can setup your own pages of gauges!
