Enhance Performance and Disable Auto Start Stop with S1000 DiabloSport Sprint AFM Module Review

Essential for anyone who has a GM & Chevy fuel management system. I bought a toggle switch (Tonsiki OBD 2 cable 16 pin M/F male to female) to be able to turn it on and off when I want/need. I leave it on around town and when towing, and just flip the switch when hitting the freeway for long trips for "better" gas mileage. Great addition to the truck!

Works great. This is in my 2010 Silverado Crew Cab 1500 LT. I got about 1 mpg more, nothing major, but I didn't lose any gas miles. The truck runs more smoothly and you get power immediately when you step on the gas without hesitation. I leave it on, it doesn't drain my battery, it turns off when I turn off the ignition. It has a red light that flashes when the car starts and turns red once plugged in.

Bought this for my 2009 Silverado 1500 because I had this lag problem going from 4 cylinder to 8 cylinder when I decided to switch . So far I've only used it for a 20 mic ride home from work and it did what it was supposed to do. I turned it on and waited for a solid red light and everything was fine. The truck definitely drives better on the freeway and off-road. I can say that it shifts/downshifts smoother and has more responsive throttle response off-line and in cruise. No more lag behind…

I wasn't one of the lucky ones to know about this amazing little gadget that you can pop in your truck and just drive before you have to replace that bolt, which Chevy obviously made. My truck was refurbished and built into this small detail and you will feel the difference 100%. I have a Chevrolet Silverado LTZ 2010. My gas consumption is not noticeable. The truck runs much smoother and I couldn't be happier. I have no problems or interference with other components on my truck. Definitely…

I love the diablo module! Smoother idle, more power and better oil pressure! I installed it on my 2013 Chevrolet Tahoe PPV. Super easy installation! Plug and play! The perfect canned tune! My truck becomes a whole different animal when I drive it. The best part is that if you want to disable the device for long gallon rides, you simply unplug it. I hope this cancels or delays a costly DOD removal repair in the future. Does not drain the battery while sitting. The LED is switched off by the…

Easy to install, plug and play! This is solely based on my experience with this device and not the opinions of others. I installed the unit as soon as I received it on the day of a very long drive. So far this drive has been highway only and I haven't had any problems. Before I bought this unit, my gas mileage averaged 14 seconds and the engine ran intermittently. Since installing this unit I have not experienced any misfires or received engine codes. Very happy with my purchase for my 2013…

2014 GMC Sierra 5.3L. Bought this truck with 20,000 km in November 2017. I wasn't happy with the AFM after a few weeks of riding. I have sometimes observed huge plumes of smoke when the ACM is turned on or off. Big blue clouds of burning oil. The dealer said he couldn't find anything. Also, the truck seemed to shift very erratically, with the AFM turning on and off frequently. So I took a chance with this AFM distance module. It's been 90 days and I'm very satisfied. The oil no longer burns…

No problems so far. idle is quiet. No loss of performance. I bought this truck in 2017, it's a Silverado 5.3 4x4 Ext. I had CK Eng Month. Missing light Really bad Went back to dealer Spark plug #1 Literally exploded. I thought I was bolted on the truck, {it had 1 owner, low mileage so I bought it} only the dealer changed a spark plug so I figured it just needed an adjustment, I changed the spark plugs {4 spark plugs including #1 looked bad) ran a little better but still had a rough idle. Gas…
