Range Active Fuel Management Disable Device Reviews


Makes your truck run like it should

Reviewed By Paul H (POWELL, WY) —5/2/2015 6:14 PM

I wish I had thought of this device. As a 38 year veteran mechanic for GM, I am not a fan of active fuel management. It causes surging, oil consumption and ultimately, early required engine repair. My '09 GMC runs smooth and quiet with excellent throttle response. Towing now is effortless. I haven't tracked the fuel economy for very long but it seems to be better. I shall have to track on the next long trip. Tired of herky-jerky and droning at 45 mph? try this product, I'm sure you will like it

DiabloSport inTune I-1000 Tuner Reviews

Reviewed By Edward D (Gainesville, FL) —5/2/2015 7:02 AM

Follow instruction closely, be patient with updates and registration. Installed canned 87 tune on 2003 Tahoe with good results. Also just changed tires and used it to change tire size. Notice good throttle response and good shift points. Haven't tried 91 tune or modified yet. I like it, plug and play is nice, it is really just a flash tuner but very nice.

DiabloSport Trinity T-1000 Programmer Reviews


DiabloSport Trinity T-1000 2014 Chevy Silverado

Reviewed By Billy C (MOUNT STERLING, KY) —5/1/2015 12:53 PM

I liked this programmer for the fact it allows you to pretty much tweak everything on the truck performance wise. The only issues I have is when you're switching between tunes you can't do it on the fly. Also you can't pick which vitals you want monitor while driving. It offers a few screens but none are really of any importance.
