Works great

Reviewed By Kevan C (Hagerstown, MD) Reviewed for a 2012 GMC Sierra —7/5/2017 2:02 PM

Bought a pre-owned Sierra 1500 with the Vortec 6200 where the previous "computer" calculated MPG was 10.2 average. I cleared the computer, installed the MPG default tune with firm shift. With 2 tanks of regular 87 octane I now get overall "computer" average of 16.7. I will hand calculate at next fill-up.
