B58 JB Plus Quick Install Tuner ....

Thank you, I'll go ahead and pull the trigger then.

Start with the dial low, see how it runs (do you have 93 or 91) then dial it up. If you feel something weird or not right, then something is weird or not right, dial it down, and check on the n54 forums.

I’ve had mine installed (factory setting) for over 1,000 miles with zero issues. You can indeed feel the difference when in place. Money well spent with no regrets.

Just to confirm, I've had a JB+ for a couple of months now on the factory setting and no CEL. Works great. Minimal additional power with no mucking about or loss in drivability. Just what I was looking for.

Question about this: As noted above, I just have it on the factory setting. I have 93 in my area and run it. Do you have any experience running one of these things cranked all the way up on 91 or 93? I honestly forgot the thing was even adjustable until you mentioned it.

I'm not a tuner, but I think you'd be ok cranking it. 4psi is the max additional boost it will provide. If you're on 93 and it feels alright, it's probably ok. But without the ability to pull logs it's a little hard to know 100%. If you try it and it feels.. off, definitely dial it back down.

I've had mine since last March and the dial has been on max since I first installed it. No issues at all with my A91 Supra using only 93 octane.

Do you actually feel the increased hp/torque?
Or placebo?

It's 4psi of boost, it's a real amount.

Yes. It's difficult to maintain traction when going WOT in first or second gear. Launching from a dig also leads to plenty of burnouts and startled passerbys.

Wanted to comment as well: Definitely noticeable. As mentioned by others, tough to maintain traction in 1st and much of 2nd after install. Not placebo. Anyone dyno after install?

Yeah it goes on the TMAP, which is on the charge pipe.

So the one on the second pic correct?

Yeah, you have an aftermarket charge pipe, correct? It's a little hard for me to see from that picture.

Yes I do . It’s the AMS one. On the stock one the sensor seats a little closer to the throttle body . For some reason the AMS one sits lower!!
