Sprint Active Fuel Management Module is rated 4.6 out of 5 by 83.
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 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 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 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 Everything works how it’s advertised I put this in my truck and the difference was amazing runs great not sluggish or confused lots of power as it should and gas mileage went up 4miles to a gallon...

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

I have the sprint module in my 2010 gmc sierra, but I am considering a 2018 silverado. My module is about 2 years old and has always worked perfectly. Do I need to update the module to work properly with the 2018 5.3 compared to my 2010 5.3?

Asked by: Dave12234

I have a 2016 Chevrolet Silverado.. I’ve been using the Sprint AFM... it works wonderfully.. Will it have a negative impact on my engine or any part of my truck in the future? Say 2, 3, maybe 4 years down the line 

Asked by: Charles949
No, it won't have a negative impact since this is a simple module that turns off the AFM.

Does this work on a 06 GMC envoy Denali with the 5.3. I bought the Range AFM Disabler which is a similar device and it did not work on mine I even tried it on my friends 07 envoy Denali. I could still feel the afm kick in and the exhaust note would change

Asked by: fcortes03
Yes, it does and you probably had a defective module. For the best price available, give us a call at the number below. 866-404-6141 DIAL 5

ALL I WOULD LIKE TO DO IS GET PAST THE 98 MPH SPEED LIMITER. DOES THIS PRODUCT DO THAT?

Asked by: MARK C
No, it does not.

I noticed warning on the box to not leave plugged in for over a day bc it may draw power if the vehicle is off. I know that on my 07 Sierra the led on the device is only on if the vehicle is on so my question is does it only draw power when the led is on?

Asked by: Gmcman
The Sprint module has a very small battery draw when the vehicle is off and in "sleep" mode. This is because it needs a monitor running to catch when the vehicle is started. This small draw is not enough to adversely affect battery life or drain the battery unless left in place for an extended period of time.

I extended my bumper to bumper, drivetrain warranty on a ‘18 6.2L High Country(7years 160km). I would love to use trinity but, don’t want to void, or get hassled about warranty. Is there any way dealer could detect this has been used? Ontario Canada 

Asked by: Peeweesmall
Our products do not leave any traces in your vehicle when you restore the original settings. In this case, the Sprint S1000 doesn't actually program the vehicle at all. If you have any additional questions please give us a call at the number below. 866-404-6141 Dial 5

Does this change the shift points? I bought it for my 2010 Silverado and it seems to drive so much better now. I actually feel like I'm driving a truck now.

Asked by: DarthFrazier
No, it does not modify shift points, the Sprint module has one function and that is to turn off the AFM. For better shifts points and firmness I recommend the intune i3. For more info and the best price available, give us a call at the number below. 866-404-6141 DIAL 5

Is there a special starting sequence?

Asked by: baddogdgs
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.
