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.

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.

2015 GMC Sierra 1500 5.3v8 Only have about 200 miles so far and my first impression is mixed. No more rough shifts and hunting in the transmission, good thing more power and smooth acceleration, good thing, reverted to 4cyl mode while driving in the city, bad thing lost about 1mpg or so, not a big deal. I don't know about parasitic power drain haven't checked for it yet, was able to get back to v8 mode by removing and reinserting the sprint device will have to wait and see if it happens again.

The Diablo Sport Sprint Module has stopped the oil consumption problem. It also resulted in smoother transmission shifting. There use to be a small bump in the transmission when it down shifted from 6th under full throttle, that is now GONE
