Once installed it made a HUGE difference on the performance of my 2015 Chevy Silverado Highcountry. Amazing results, now I can burn rubber!

Installation requires a software download. The unit is not Mac compatible. It requires a workaround remote session with a bully dog tech controlling your personal computer. Also, final setup is not self explanatory and the instructions are vague. It takes trial and error to figure out. I do get 5% better gas mileage 5.4L V8

Great product. Easy to install. I'm running 35s and can already notice a significant change in shift points and power. Can't wait to start downloading custom tunes to unleash the beast!

I have a 2016 Silverado crew cab z-71. It's no secret these trucks are underpowered. This tuner dramatically improves off the line performance and my fuel economy improved by 3mpg in town and 4 on the highway. The improvements in the transmission shift patterns are very noticeable and I'm looking forward to see what this does for towing capability.

Unit does a great job of monitoring the engine and various other statuses but could use a ton of improvements in engine optimization. I really think they were overly cautious when programming for Nissan. Granted, I have a 4 cylinder so wasn't expecting massive gains but am very disappointed because I know this thing could do so much more.

Very easy to install, I even hard wired it into the fuse block under the hood so it works on/off with the ignition. Over all it's a great piece of machinery. I was able to turn off AFM, which is great. Also programmed it to performance tune on engine and trans, and within 2 tanks of fuel I am seeing a 3 mpg increase, that's awesome because I was only getting 12.6 before the programmer. AutoAnything even lowered the price for me, so don't hesitate to chat with someone and ask!!!
