2011 AVALANCHE tune
Easy to install but be sure to follow instruction. (Pull proper fuses). Disconnect (8-4 cylinder) drop out. You will have a smother , quieter and more responsive engine. There are also two options to try the premium option and the regular option I have yet to try their premium option but I am very satisfied with the regular option. For my money it was well worth it.
Hyper tech 2.0 programers
I bought this to bypass the G.M. Active fuel management system. Instead of going to the stealership I purchased this programer to set the computer to the v-8 only setting. This repaired the 4 engine codes I had set on my computer. The Avalanche kept turning off the fuel to four cylinders and setting the check engine light . The engine runs great now and this is a bargain 20 minute repair to program the computer. Ten days now the 5.3 runs like a top and no codes . Thanks Again!
Instant results, extremely easy to use.
Main reason for my purchase was to give my 2007 Chevy Avalanche a little kick when either accelerating from a dead stop or getting onto a freeway. Being only a 4 speed, I noticed my Avalanche "lagged", for a lack of a better word, when getting onto a freeway and trying to accelerate to freeway speeds. I wasn't expecting a huge boost, but I definitely noticed an increase in power when I put the pedal down. Fuel economy stayed the same if not increased, highly recommend this product.
