not worth the asking price but works.

its alright does what its supposed to do and tricks the computer into being under load to run at v8 mode all the time. doesn't solve rough idle issue doesn't increase hp or mpg it only removes the v4 mode. thats it. not worth the money but you got 3 options ,this, the other brand, or buy the tuner. wish i would of bought the tuner now instead of later. if your tight on money but really want your v8 to be a v8 then this works .. but needs to be ALOT cheaper.

Absolutely love this device works great. I plugged it in and the light stayed on until I started the truck for the first time. Then the light shut off when I shut the truck off. Truck sat for a week no drain on the battery.

I purchsaed the Diablo Sport because I was fed up with the active fuel management dropping from eight to four cylinders. After I recevied my Diablosport and installed it I instantly could tell the difference. I have notice the increase in my miles per gallon since installing the module.

Works buuuuut,

This little guy here does work as advertised, but honestly for the price I really expected a little more. I read posts that raised my expectations like a little more power, but all that is noticeable is that you have a true V8, plain and simple nothing more nothing less.

808 - DiabloSport

Anything auto is awesome. Shipping was fast and well packed to Hawaii. Open the DiabloSport sprint, plugged it in and no more V4 mode. Truck runs like a V8. As far as battery drainage I haven't had any problems. My truck will sit for 2-3 days and start right up. With the key off the red light turns off.

2008 5.3 v8 afm what a joke

I've had the Diablosport for a short time. And I think it's money well spent. Makes my v8 stay in v8 mode the way a v8 should. Thanks Diablosport.

Works great , no check engine light, V8 mode constant. N

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.

Goodbye AFM, Hello Full Time V8

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.

Diablosport Sprint AFMM

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.

Diablo Sport Sprint Module Review

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
