"Out of all tuners I have installed this is the best our customer is in enforcement,this made vehicle a pursuit capable 2011 sport utility, performance is a way of safety when used with good common sense. Thanks for a great product!!" —Harold D from Spring Hope, NC bought a Hypertech Max Energy Programmer for a 2011 Chevy Tahoe, 5.3L V8.
"I would rate "Excellent" - however, let me explain why I can't. The device looks like an iPhone, but it has the weight and feel of a cheaply made plastic device, not the heavy duty weight and feel of a good quality iPhone or Android type phone.
Ok, other than the cheap plasticy feel of the device, it works great. Plug it into your computer, and it updates itself automatically from Diablosport's website with the latest tunes and updates.
Plug it into your vehicle, load the tune up, and you're good to go. Very easy. The best thing about it is defeating some (most) of the torque management that GM builds into their factory tunes, and also being able to disable AFM (Displacement on Demand) - that stupid 8 cylinder to 4 cylinder mode. That ALONE is worth buying this device.
So while I can't give it a 10 out of 10; it would certainly rate a solid 8 or 9. If Diablosport would upgrade the device's case and make it a heavy duty metal or lightweight alloy, similar to the iPhone - then it would be a 10 out of 10." —Brad B from Martinsburg, WV bought a DiabloSport inTune I-1000 Tuner for a 2011 Chevy Tahoe, 5.3L V8.
"Used Cortex Programmer with, K&N intake, and Magniflo muffler. Around town MPG improved 1-1.5 and Highway about the same. More power, shifts are smooth and engine sound is awesome. Programmer was easy to install and I am not a car buff. Once you program the computer you un plug it and are good to go." —Timothy S from San Jose, CA bought a Superchips Cortex Programmer for a 2011 Chevy Tahoe, 6.0L V8.
