Unleashed the POWER of my 2012 Silverado 1500 4wd!!!

Reviewed By joseph f (SUMTER, SC) Reviewed for a 2012 Chevy Silverado —2/26/2015 9:12 AM

plug and play...this tuner literally unleahed the beast in my Silverado. I deleted the AFM system, set shift firmness to 50%, and tires set to 35"!! She RIPS down the road now. No irregular shift going downhill!!! THE MOST IMPORTANT is my MPG went from a dead on 11.5MPG to 15MPG. ALL is perfect now!!! BUY ONE< YOU WONT REGRET IT!!!!!!!!!

Words can't describe the change in the truck. Quite power. Really have to watch the speedo. Shoots to 90 mph in nothing flat. Using 87 OCT. canned tune at this time. Will go with a custom LEW tune when it warms up. In New England, BRRRRRRRRRRR!!!!

I didn't notice much difference

Installed on 2012 Chev 2500HD gas. a bit confusing on how to install download and what to/not to load. I'm still playing with it. it is not on the fly. takes 10-15 min to change program with fuse removal. about 10% better mileage (10% of 11 mpg is only 1 mpg)I was hoping for at least 15mpg. display small hard to see, I like how I can change the display to what I want to see. Driving coach a neat toy. I have had programmers on diesels and there is a big advantage. Not so for gas.
