inTune i3 for GM is rated 4.0 out of 5 by 24.
Rated 2 out of 5 by from Poor Quality i have a 2017 chevy silverado 5.3 6 speed trans I have had nothing but problems with this device when i first got it it was frozen on the screen, called tech support 4 times took the 4th time for someone to actually help me and get it unfrozen the second time i called a guy hung up on me. now my problem is whenever i click on the dod/afm on/off it just freezes the whole device so now i cant turn off AFM which was the whole reason i got the device. i have had a lot of different tuning devices on multiple vehicles and never had this problem. Other then that the tune is slightly better then stock. And does offer a Scan tool built in which is pretty nice

Rated 1 out of 5 by from No difference. Had it installed for 2 weeks on my 06 GTO 6.0L and felt no difference at all. Only change is I went from 19 mpg to 12 mpg with no change in driving habits or conditions. Removed the tune and it runs better. There is no way to customize the tune yourself besides changing the idle and a couple small things. I have full exhaust from long tube headers back with an aftermarket intake and hoped for a huge difference like Cobb does. But, no. It plugs in and uploads and adds gobbs of timing. That’s it. You can data log and send that to a custom tuner if you wanna pay More money for that. I’m currently selling mine and going to get a real dyno tune for real results. Don’t waste your money.

Rated 5 out of 5 by from Intune i3 for GM Bought to delete AFM / DOD on ‘09 Tahoe, ended up putting the 87 octane tune with firm shift....really helped it out...much more fun to drive and definitely helped the lame shifting 6 a different vehicle now. Added a license for my Suburban, technical support was great on that part. Very pleased with this tuner!

Rated 5 out of 5 by from Great tuner Bought this for a little more power and mainly better furl mileage after adding 37s. Went from 9 back to 12 mpg and gained some low end torque. Pretty pleased with the canned tune. Havent tried running the diablo tune yet i always run 87

Rated 4 out of 5 by from Exicited to see results. Just purchased intune i3 for my '11 GMC Sierra with 5.3L, 6sp auto, 4x4. very important to update tuner before you plug into truck to ensure you get latest and greatest. Took 5 min to update on wifi. I plugged it into my truck and followed the instructions. Took another 5 min to download tune to truck. Not as easy to find how to disable AFM/DoD and remove speed limiter but i figured it out. I chose this product based on feedback on blogs and customer reviews from local guys that used this tuner. So far, I'm happy!

Rated 5 out of 5 by from easy to use I installed the 87 octane tune in my truck, a noticeable difference in the performance. Go a 2.5 mile per gallon increase in fuel mileage.

Can this remove the factory speed limiter  on my 2012 silverado?

Asked by: Matt6612
yes. I just used it to disable the AFM/DOD, remove speed limiter, change tire size, firm up auto shift and 87 octane tune after install of a CAI and catback exhaust.

Can this tuner adjust for tire size like the predator 2 and trinity 2 programmers? I assume the answer is yes, but I didn't see it in the product description.

Asked by: Alex83188
Yes, it has the exact same parameters for GM vehicles as the P2 and T2.

What are the #’s for 2015 Chevrolet Sonic ?

Asked by: Steven_88

Does the i3 tuner need to stay plugged onto the OBD port? I have a 2010 2wd tahoe w/5.3L. What about when I have to go to get it emissions checked? I just want to lose the AFM, speed up throttle response and firmer shifts from the trans.
