Sprint Active Fuel Management Module is rated 4.6 out of 5 by 68.
Rated 5 out of 5 by from Sprint review I bought one of the competitors units from a 3rd party vendor but they were on the approved vendor list so when I started have problems with it I contacted R@#&e who told me I had to work with S%$#t and neither one wanted to help me out, I gave the thing away to a NNBS owner and it worked fine for him, the Sprint I bought from Diablo has worked flawlessly in both my 2016 Silverado and 2014 Camaro SS, thanks for a great product , I highly recommend it for the person who only desires to rd their ride of the evil AFM without voiding their warranty.

Rated 5 out of 5 by from easy to install my gmc sierra was always downshifting in 4 cylinder mode and drive train would clunk in town on downshifts. and it used oil. The diablo sprint module helped with oil usage and it also stopped ruff downshifts.after I put module in it. It runs smooth now and goes up hills effortlessly without downshift at 60 miles a hour. I am 71 and I really would recommend this to gm 5.3 owners. I have been leaving it plugged in up to three days setting in garage and it has not drained my battery. Thanks diablo. I am a lot happier with my gmc now.

Rated 5 out of 5 by from Did everything I wanted it to! V4 mode begone! My 08 Chevy w/ 200k+ miles seemed like the AFM was getting bad. I was getting tired of a harsh vibration coming from the engine every time I slowed to a stop. This was an awesome and easy fix. I really enjoy it so far. Not sure if it really changes the delay with “pedal to go” time, but it does seem to have a little more power in third gear. Completely surprised me. I was a little worried about the battery problem I was reading about but I’ve had no issues at all. Thanks guys, it almost feels like a different truck. Oh and my mileage has stayed the exact same. -15.2mpg

Rated 4 out of 5 by from 2017 Camaro SS I was feeling the hesitation regularly at cruise on a slight incline. I bought the Sprint and installed it. Easy install, lights on it go dark when car is off and locked, so it looks like no battery drain. Car stays in V8 mode now, no fault lights or indications. Reason I only give it 4 stars is it didn't totally eliminate the hesitation. It still happens, but rarely now. Could possibly be something else causing it. Power feels good all the time now. Haven't really noticed fuel economy decrease, although I do a lot of rush hour driving. Definitely recommend to any Camaro SS owner.

Rated 5 out of 5 by from Does what it says! I bought this hoping it would just get rid of the Active Fuel Management, but it did so much more. My Engine is running better, I gained about 2-3 MPG from the stock config, no more stupid exhaust buzzing, and dare I say a tad bit more power from my truck. I also took it out and put it in my wife's rig and it worked great in there as well. I would highly recommend it!

Rated 5 out of 5 by from Works flawlessly I bought this for my 2016 camaro ss. This thing works like a charm, not cels or weird issues. Over 1000 miles driven installed, turns off with ignition turned off. Going to send everyone that has a gm that hates afm to get one from diablosport.

Rated 5 out of 5 by from 2013 silverado--- works great, shuts off w/key off The only thing I got to complain about is the price, this module works great so far, no CELs have been set and the 4 beater mode hasn't came on at all. Shuts off with the key off and doesn't need a pass through cable for my 2013 anyway

Rated 5 out of 5 by from Worth every penny Had problem with gmc 5.3l fouling plugs and burning oil during hard acceleration from v4 mode. Changed plugs and plugged the sprint unit in. No more oil burning, No more fouled plugs, and better performance. Win all the way around. already told all my friends with AFM DOD about it. Thanks.

Is there a special starting sequence?

Asked by: baddogdgs56
On the GM vehicles, there is no special sequence. We do have a timing obstacle that has to be addressed on the Dodge vehicles but the GM doesn't have that kind of issue.

Will this work on a 09 5.3 or what would you recommend

Asked by: Ace auto 1
Yes, this will work for that vehicle. If you are wanting to go with something that isn't going to add power but rather just turn off the factory active fuel management feature where it goes down to 4 cylinders, then this is the perfect product. If you are wanting something that adds horsepower, you may want to look to the 8245 inTune i3 Platinum as it will give you active fuel management features along with horsepower gains and a host of other options.

I bought a new 2018 GMC SIERRA DENALI WITH A 5.3 Will this void my warranty?

Asked by: TRUCKMAN
The Sprint should have no effect on warranty whatsoever. It doesn't modify the vehicle and when you remove it from the vehicle, there is no trace that it was there. I'd just recommend removing it from the vehicle prior to taking the vehicle in for service.

When I plugged this into the OBDI port on my 2013 Camaro SS and started driving I got an error code: Oil pressure low - stop engine. It only produces that code when the Sprint AFM module is plugged in.Is there something I can do to prevent the error code?

Asked by: Stone
I have not seen that issue up to this point. Please contact our tech support so we can further investigate this issue. 866-404-6141

Is the sprint AFM module compatible with more then 1 vehicle, or is it married to one vehicle? 

Asked by: Hunter28
It doesn't vin lock but the tool has to be connected at all times in order to function properly, but you can always disconnect it and plug it into a different vehicle to disable the AFM.

Will it shut down the speed limiter ?

Asked by: Marquezz
No, the Sprint module controls the DoD/AFM only. To raise the speed governor, you would need to purchase a Predator 2 or inTune I3. They have the ability to turn off the AFM and raise the speed limiter in the same device.
