Works as advertised

Reviewed By Ronald B (Stevensville, MD) Reviewed for a 2009 Chevy Avalanche —11/22/2016 10:45 AM

My 2009 Avalanche runs very smooth now, acceleration is steady and I have not noticed a significant decrease in fuel economy yet in 200 mile yet.

Run with the Devil

Reviewed By Gregory M (La Place, LA) Reviewed for a 2009 Chevy Avalanche —9/12/2007 7:36 AM

I installed the DiabloSport Predator tuner 93 Octane tune in my 06 Trailblazer. The install was effortless and quick with the exception of the fuse removal. The truck responded with improved instant excelleration and improved transmission shifting which was my only complaint about the truck prior to the install. This is a great product and probably the easiest bang for the buck performance wise that can be done.

Goodbye AFM, Hello Full Time V8

Reviewed By David M (ANN ARBOR, MI) Reviewed for a 2007 Chevy Avalanche —3/28/2017 8:41 PM

I was a bit hesitant to buy this product as there were no reviews for it, but for the price with coupon I couldn't resist. device works perfect. Simple plug and play installation to disable the AFM. My v8 is finally a full time v8. My only complaint would be the red lights on the unit. It lights up the floor at night.
