What issues were you having with the JB4/stack? I keep hearing I should do this but I love the set-and-forget tune even if it isn't maximizing power with a few more pounds of boost.
A few things were happening:
On full throttle pulls in 3rd gear I intermittently got some bad knocking at 5000+ rpm. I'm still not convinced this is sorted out, but I don't have a great way to log, until the Uniconnect logging started.
My brother had a similar car with APR/JB4 stack. His boost values were much more consistent over the course of months of logs, but mine with the Uni tune would not produce consistent boost curves. I understand environmental factors played into this. He ran a 11.99 1/4 on his APR/JB4 tune, so the potential is there. He also only owned the car for 18k miles where I plan on owning for many years.

My idle was kinda garbagey with the JB4. Stumbles mostly. This went away when I uninstalled the JB4. Even happened on Map 0.

I finally came to the conclusion that I don't need to go beyond the Unitronic tune. The car is fast enough, and after I started chasing fractions of a second in the 1/4 mile it was not any more enjoyable to drive. I am at a point where set it and forget it is just what I need.

I do want to say that the Jb4 was a great product when I was on a stock ECU tune and IS20. Things just got less than desirable after I stacked. Different experience than APR/JB4 stack for sure.

The JB4 stack is intriguing to me but like you, I love the set and forget you get with an OTS tune.

They are metal inserts that go in to the bushings of the rear subframe of a 4mo car. Google it up and look at the install sheet. It's very apparent there.

Homelink self-dimming compass mirror engage! Picked it up used by luck on the GSW/AT Facebook buy/sell group. Really slick - I really missed a self-dimming mirror especially with all the CUVs/SUVs on the road and me sitting lower to the group. Being able to remove my ugly garage door remote is also a plus. Compass is also a nice touch to finish it off. Install was straightforward but truth be told I broke my @#$# light switch removing it for whatever reason my brain wasn't there that morning....replacement en-route from shopdap.
Did you have to the cable through the A pillar trim? I have the part here but am nervous about that part.

Yes but it's very simple, I didn't even remove it...just pulled it back and tucked it in.
