Dang. I didn't realize there was a 500 character limit. So I will keep this short and sweet. Power 5 Ease of use 5 Tuneability 4 Instructions on what does what 3 If you don't care about your 0-60 times and yada yada buy this tuner. Oh! Do NOT adjust your tune if you have smog/state inspection coming up. They don't tell you that if you adjust parameters you will fail. It took about a week for my truck to go through the "GM cycle". Great buy, autoanything rocks

Bought this to correct my speedometer and to get a little more power. I had to update the software on the programmer but after that it was easy to install and use. Good value.
