Description

Driving in V8 mode shouldn’t be something you can enjoy only once in a while. So, keep your 8-cylinder running to the best of its abilities with a DiabloSport Sprint Active Fuel Management Module. Made to disable the factory Active Fuel Management (AFM) feature in your 2005 to present GM ride, the plug-n-play Diablo Sprint stops your cylinders from dropping and reducing power.

If you’d love nothing more than to eliminate that hesitation on acceleration and remove that annoying exhaust buzz from existence – a DiabloSport Sprint Active Fuel Management Module is just the right accessory for you. Not to mention, the DiabloSport Sprint AFM delivers unrestricted performance without the need for reprogramming or re-flashing your ECU. Your DiabloSport Sprint Active Fuel Management Module comes with a 1-year limited warranty.

Only issue I had was shipping, their next day delivery is a slow boat from China! Takes several days to get so don't pay extra. Product was packaged very well, just plugged into obd2 and automaticly connects to onboard computer. I leave mine plugged in 24/7 with no battarie issues, shuts down when ignition is off. Gas Millage is around 17 MPG city. I purchased because I wanted the full power all the time, and do not want to ever pay the cost of several thousands to fix or replace an engine.

Good product by Diablo Sport

I bought this to see if it would slow or stop oil consumption. I have 1000 miles on after install with a fresh oil change. Still shows spot on full whereas normally would be 1 quart low. Added bonus is it feels like I am driving a totally different vehicle not having it alternate between 4 and 8 cylinders constantly.

Does it's job. Enjoying the consistent power.

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.
