Yeah, the sensor position isn't super important. it's the not-round sensor on the CP. The round one is a temp sensor. You want the square-ish one.
JB+ increase boost pressure pretty steadily. You'll get ~4psi of increase across the band.
What @zrk said. I have a JB+ on my untunable 2021 and it's been great. Definitely makes the car a bit quicker and there's no mucking about with settings. Since it's a static boost increase across the power band, it doesn't hurt drivability at all. I have put my car on both the track (NCM) and the drag strip with the JB+ installed. Never had any issues related to its installation. What specifically do you want to know about the mod and tracking?
Though I've switched over to ECUTEK and a Pure800, the JB+ is still my favorite bang for the buck mod due to the instant increase in power, its ease of use, and retaining the factory warranty.
Gah… I’m so conflicted. Every time I think I’m going to get and install one of these, someone here says how they’re not worth it, will blow up my car, or bring about a universal apocalypse the likes of which mankind has never seen before!
No not really, I've got a JB4 on mine since last June and haven't had any issues. Never went above Map2 (+4 PSI, IIRC) until I got a custom map6 done last week.
I don't have map 2 pulls, but I do have some map1 pulls from 30-80 mph. AFR is around 14.5 on WOT, and boost was peaking around 19 PSI there. Checking through my map6 on 3rd gear pulls, AFR is largely the same and boost peaked around 21.5 PSI.
Never reached out to Burger for the high boost readings, but I did see some old threads that state stock boost is 12 PSI. All the readings seem consistent with subtracting 4 PSI to get the amt of boost actually being achieved.
