Wow!!! So worth it!
This made my little 2.7 scream. They rpms stay in the sweet spot of power. I had an intake and exhaust installed and this box was the icing on the cake. No joke. So much more fun to drive. Wish it had the speed calibrator, (22in wheels) some do some don't. I read a forum and it installed easy the first time.
I installed this tuner on my 6.0L gmc in about 30-40 minutes, it was very easy, the tunes load quick. MPG about + 1-3mpg city depending on how i drive, better throttle response, noticeable power gains, driving coach helps with improving mpg. DISLIKES... the screen is a little small, and you can only choose from 3 tunes. 1.stock tune(factory settings) 2. Regular(LOW-MID octane) 3. Premium (HIGH octane) I would have preferred a economy, towing, and performance tune selection.Also i dont see a way to select aftermarket acc. installed on my truck(such as CAI, EXHUAST..) which other models have. OVERALL THIS IS A GREAT PRODUCT WITH IMPRESSIVE RESULTS... I RECCOMEND THIS TO ANYONE LOOKING FOR POWER, MPG GAINS, AND OVERALL DRIVEABILTY OF YOUR TRUCK!! p.s. dont get to attached to your rear tires... chances are they wont last long with the added power!!!!!
Not as advertised
Great product but not recommended for the layman. If your not familiar with tuning a vehicle before hand then adv do your research. Hypertech was not forthcoming about what the product can and can't do for the vehicle as well i.e. does not work with certain after market mods.I had installed a bigger throttle body which caused the engine to go into a lean mode after using hypertech tune ( not matter how hard I tried I couldn't resolve issue without falling back to default stock mode). So if you have a stock engine with no mods ( other than a cai or cat back ) then your clear.
