Works great. No codes. Ride is was smoother now that it's not switching between 4 and 8 cyl.

I was a little sceptical about buying this tuner because it was fairly inexpensive. After receiving it and trying it out I'm amazed how well it works for my 2001 denali. I tuner the mileage saver and so far I'm getting at least 2.5 miles to the gallon better. Can't wait to try the other functions..... If I were you I'd buy one
