Hypertech Max Energy Programmer Reviews


Hypertech programmer is a quality product.

Reviewed By Gary R (CASPER, WY) Reviewed for a 2003 GMC Sierra —3/29/2015 4:58 PM

Easy to set up. Easy to program vehicle. Better acceleration; better power; some increase in MPG. Almost like having a new truck.

Range Active Fuel Management Disable Device Reviews


Does exactly as advertised!

Reviewed By John B (CONROE, TX) Reviewed for a 2008 GMC Sierra —3/27/2015 5:53 AM

I was trying to disable the AFM simply because the switch from 4 back to 8 cylinders was causing my 5.3 to burn oil. Hopefully I've gotten to it before the rings stick. The range device just plugs in and no more 4 banger. Great product and the simplicity is nice.

DiabloSport inTune I-1000 Tuner Reviews


lots of adjustments

Reviewed By daniel b (akron, NY) Reviewed for a 2014 GMC Sierra —3/25/2015 3:07 PM

pretty nice tuner for the money. a bit complicated without much info sent with the tuner to know what some changes are. iv had three different Hypertech programers over the years and feel this has a more noticeable power improvement.
