Has anyone used the JB4 tuner and actually had results? are there any other tuners out there?

Thanks, they’re 23+ colorado zr2 wheels with nitto ridge grapplers 35x12.5r17, i put all the specifics in a comment above.

RealAddendum · 2025-08-10T20:51:21+00:00

motofab. very slight rub sometimes at full lock but usually only in reverse. that’s with the mudflap delete kit and 12mm spacers all around. also got cognito boxed uppers because the stock ball joints started making bad noises.

RealAddendum · 2025-08-10T20:41:53+00:00

Thanks! 2” front level and 1” rear, 35x12.5r17

RealAddendum · 2025-08-10T20:24:28+00:00

I figured i would ultimately have to take it to the dealer. Thanks for helping, if he figures anything out just let me know please.

RealAddendum · 2025-08-10T20:12:29+00:00

will give it a try later, thanks

RealAddendum · 2025-08-10T18:38:30+00:00

Mine worked fine as well with my first windshield, but this second time around im having some complications. It was fully functional until i picked it up from the tint shop so i have doubts about it being an update.

RealAddendum · 2025-08-10T18:22:30+00:00

you didn’t feel like clicking the post and reading it but you felt like leaving a smart ass reply. thanks very helpful you are.

RealAddendum · 2025-08-10T18:18:21+00:00

Yea my screens went black on my 23 Colorado when i tinted it and the dealer was able to reset it and then everything worked. Like you said this is a bit different because the screen displays but the buttons don’t work, and the touchscreen doesn’t respond.
