"It works. No more lag from V4 to V8--just instant, smooth power. The best part is not having to hear how bad my aftermarket exhaust sounded in V4 mode. Also no change in MPG! AFM is a crock." —Gary R from Seabrook, NH bought a Range Active Fuel Management Disable Device for a 2012 Chevy Silverado.
"Apparently DiabloSport has some real code-heads, because the InTune I-1000 is a brilliant little device that allows you to install 87 octane tunes, performance tunes, MPG tunes, etc. Shifts can be firmed up, shift points increased....you could spend a whole weekend playing with this thing and still not try everything. Great bang for the buck; highly recommended." —Louis H from Raleigh, NC bought a DiabloSport inTune I-1000 Tuner for a 2012 Chevy Silverado, 5.3L V8.
"I bought this primarily to correct my speedometer to compensate for the 35" tires. Hypertech has a speedo only module, but it's $200 so I figured I might as well get the ability to deactivate the Active Fuel Management mode if I ever decide to add an aftermarket exhaust. Additional HP is pretty minimal really and only during WOT. Fairly expensive for what it does, but that's the same for all programmers." —Robert S from Aurora, MO bought a Hypertech Max Energy Programmer for a 2012 Chevy Silverado, 1500, 5.3L V8.
"My truck is a 2010 Chevrolet half ton with the 5.3 ltr.
I have had the unit about a week. I can tell a difference with daily driving but I did disable the fuel management and have not pulled a trailer yet.
Based off the truck computer, I am getting a little better gas mileage.
I am going to enable to fuel management to see how things go." —Thomas E from Little River Academy, TX bought a Hypertech Max Energy Programmer for a 2012 Chevy Silverado, 1500, 5.3L V8.
"This is my second truck to use hypertech on i like everything about them.i will continue to use them hope the come out with even better upgrades,that will b a tough one to do since it already does so much." —Larry L from Odessa, TX bought a Hypertech Max Energy Programmer for a 2012 Chevy Silverado, 2500 HD, 6.0L V8.
"Plugged this into my 2012 Chevy silverado and loved the outcome. Every time I step on the gas I am in v8 and crazing around town as well. Fixed my lag time when stepping into the gas from the switching afm. Works great, best part is my mileage on highway went up a little and town is relatively the same." —Travis S from Cincinnati , OH bought a Range Active Fuel Management Disable Device for a 2012 Chevy Silverado.
"I AVERAGE 1.5 MILES MORE PER GALLON . THIS IS A BIG SAVINGS AS I DRIVE APROX 30,000 MILES A YEAR . THERE IS A LEARING CURVE AS HOW YOU DRIVE AND KEEP IT FROM SHIFTING IN AND OUT OF V8 TO V4 MODE. THE FLATTER THE TERRAIN YOU DRIVE IN THE MORE YOU WILL LIKE IT . ALSO IT IS SMOOTHER WHEN DRIVING AT HIGHWAY SPEEDS" —Joe M from Avon Lake, OH bought a Range Technology Active Fuel Management Chip for a 2012 Chevy Silverado.
"Easiest performance gains for the money. Installation was simple. It's like getting a new truck." —Tim C from Oakdale, CA bought a Superchips Flashpaq Tuner for a 2012 Chevy Silverado, 5.3L V8.
"Easy to install. Easy to setup and operate. Hardest part was locating which fuse to hook power to." —Brian M from Bailey, CO bought a Bully Dog Triple Dog GT Tuner (49-State Legal) for a 2012 Chevy Silverado, 6.6L Duramax.
"Recently purchased this item received it even sooner than expected. I found the item very easy to install in very short order . This programmer has. seemed too increase the throttle response quite.a bit only set on level one ." —Martin O from Millington, MI bought an Edge CS Evolution Programmer for a 2012 Chevy Silverado, 6.6L Duramax.
"This programmer flat out works GREAT! You may have to spend a week or so dialing in your tune but once you get it you will thank Diablo Sport. My 12 5.3 Silverado runs 1,2 and midway through third gear with Ecoboost and that's a 360hp 420lb/ft torque truck. In fact my truck pulls harder through 1st gear and 2nd gear, its not till 3rd gear that the Ecoboost starts to pull away.I have exhaust and CAI but the programmer links it all together and wakes this beast up. Also get 21-22 mpg at 75mph" —Anthony J from Canton, MI bought a DiabloSport inTune I-1000 Tuner for a 2012 Chevy Silverado, 5.3L V8.
