At 14-15psi max you must be stage 1 I assume?
Thanks - it's rough and was my first ever attempt at fiberglass work. Yeah, it's dimmable, but I hooked it up to the hazard light button, so it's dim when it's on (enough to see at night though). The amusing part is that if I hit the hazard button, then the gauge flashes bright/off/bright/off. haha

I have the Polestar tune on mine.

Well it turned out great, color matching looks excellent.

I've read where guys have wired to the hazard button. I've been considering doing what this guy did HERE.

I wasn't aware that Polestar offered tuning for these old cars, good to know. Pretty respectable "optimized" numbers.

Where does your boost peak at in 1st and 2nd?

Do they do it wirelessly? Or do you send in ECU/bring vehicle in?

I don't mean to be nosy, but what did the tune cost you?

Thanks. The color matching was done at Home Depot, I gave them my fuse box cover (side of the dash) to match to, then got a tiny $2 jar of "sample paint". Yeah, it's house interior paint, but it worked out ok.

Wiring it to the hazard light can be done, but then you'll have a pretty dim gauge. It'll flash bright/off with the hazards too. :D
You could probably find the source of the power to the bulb and tap that, or pull it from the LSM instead, and get it to dim with the gauge dimmer (also works if you do the R/Classic cluster swap).

Peak boost is around 14-15 per the gauge, not sure if that's in 1st or 2nd. In those gear I don't watch the gauge if I'm on it that hard. haha
I dropped my car at the dealer and they flash it and I think it cost me around $800 a few years ago. HUGE improvement, mostly in transmission tuning, imo.

I'm sure there are cheaper and higher performing tunes, but I needed reliability (start the car in Death Valley in the summer, and Alaska in the winter sort of stuff) and none of the other ones seem troublefree and THAT reliable, so Polestar it was.

I'm super late to this but a while ago I PM'd you asking about your build and you were kind enough to respond. I just wanted you to know I really appreciated it. This forum and you guys are the best!
