inTune i3 for GM is rated 4.0 out of 5 by 35.
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 Sport tuning made easy Been wanting a ca legal option for tuning for both our 07 Suburban and 02 Corvette. After working with tech support to get the updates to firmware I was good to go. Suburban idles better, shirts set to firm, disabled AFM, calibrated speedo to correct rim and tire size, went with Diablo tune power and torque is improved and mpg is up also. Real world improvements on our daily drivers, that keep them streetable and legal, with an edge up on above factory performance. Will be getting the license for the corvette next

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 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.

I'm upgrading my 5.3 to a bigger cam with a few other bolt ons, I was wondering if this would be a good tuner

Asked by: Outlaw 333
You'd want to consider the 8245 tuner as your setup would require custom tuning in order to accommodate those modifications. The 8245 has the ability to load a custom tune written for your kind of upgrades and that would be your best bet.

I'm interested in this for doing a simple 87 octane tune, to help with occasional towing, & adjusting for larger tires (shift points). Does this work with AFM, or just disable it? What kind of benefits can I expect? (2015 sierra 1500 5.3, 275 60 r20).

Asked by: Scotteyv
You have the ability to keep your AFM on or off. I have a 2015 Silverado 5.3 with the same tire size.. Buy the tuner, you won't regret it.
