seems to do the job

Reviewed By jeff l (POTTSTOWN, PA) Reviewed for a 2003 GMC Envoy —8/22/2013 10:56 AM

I purchased this for my 2003 Envoy XL 4.2L V6 for towing mostly. I also have a K+N cold air intake. My wife and I have noticed a difference in shifting gears, lower RPM's in regular driving and towing, more power where it needs to be, but have not seen a drastic change in fuel economy. Have only had it installed now for 3 weeks. I would certainly recommend this to anyone.

2011 F-150 6" lift with 35" tires

Reviewed By Curtis G (BIG SPRING, TX) Reviewed for a 2011 Ford F-150 —7/28/2015 8:12 PM

Shipping was fast, installation was easy. With a lift and big tires my gas mileage went down, naturally, but its not as bad as I though it would be with the tuner. Highway on mileage xs is 14. The tire size was a little tricky, had to mess with it a bit but the closest I got on the speedometer at 75mph is 77 by radar. I can deal with that. Overall I am happy with my purchase.

Does what it's suppose to

Reviewed By Daniel T (Iowa Falls, IA) Reviewed for a 2011 Chevy Silverado —7/25/2015 10:19 AM

It works likes its suppose to. Shuts off the AFM so the truck is always in 8 cyl mode. It has come loose a couple times though so the AFM kicks back in.
