  1. B58 JB Plus Quick Install Tuner ....

    Definitely noticeable and worth the money. The only other thing I have aside from the Jb+ is an ARK DTS exhaust. I've been considering upgrading to jb4 but I read some stuff about some people not liking the power delivery from it..? I enjoy the Jb+ and the way the car feels so not sure if I'll...

  2. Puff of smoke when coming to a stop

    If you want to be sure about the dealership not overfilling, just drain it all, then refill with exactly the prescribed amount. Honestly it seems like some mileage may be the cure, if you search the issue it's difficult to find any cars with mileage experiencing the issue. The reason I figured...

  3. Puff of smoke when coming to a stop

    I gotcha, I have a catted dp, exhaust and jb4. Im gonna do an oil change this weekend(even tho dealer just did one on monday) incase they messed up

  4. Puff of smoke when coming to a stop

    I am pretty sure mine was due to some oil getting into the intake or temporary pcv issue. Mine hasn't done it since the first month or two I had the JB4, meth, and catless exhaust.

  5. @Xyare Daily Build

    Trying to get a bit more motivated/organized with my build and figured sharing it with others would help a bit. Bought a 23' auto on Oct. 1, 2022 and have been loving it ever since. Started with some bolt-on/power mods but will be looking to do more aesthetic moving forward. Engine: -Megan...

  6. Selling the Supra - Advice pls

    So I decided to move on from the Supra. Carmax offered 46k. I went to KBB and I offered 50k. The dealership guy said "yeah I can make that happen easy". Do I go higher or take the 50k..? 52k-54k I'd run out skipping but that sounds hella unrealistic with 21k miles on it already. My specs...

  7. Check out my logs?

    Hi! finally got the Jb4 in. 21 supra 2.0 running on e15 same tank for both logs. Only have AWE catback exhaust. Map 2: I believe my log looks okay, but I feel like my boost peaks way too high. And is my AFR sitting in the right space or do I need to target a richer mix? Something just feel...

  8. Check out my Logs?

    Hi! finally got the Jb4 in. 21 supra 2.0 running on e15 same tank for both logs. Only have AWE catback exhaust. Map 2: I believe my log looks okay, but I feel like my boost peaks way too high. And is my AFR sitting in the right space or do I need to target a richer mix? Something just feel...

  9. What Should I Do Next?

    To preface, yes I’ve read the pinned thread about ways to increase power in our vehicles. I currently have the following done: AA Catted DP MST Intake JB4 FTP Charge Pipe Blitz Strut Bar What’s the next step? If I go exhaust, I’m hoping to keep the valvtronic feature but do I truly expect...

  10. Manual Tuning Options

    I Think you should drive it in stock form first . Take the car to its limits then deside what ya want to do . Dont put the cart before the horse . Unless you are or have experence Racing

  11. Boost leak?/bad turbo?

    Sorry I meant no smoke coming from the exhaust, it doesn’t always make this noise, when I removed the jb4, it had actually stop making the noise but after awhile it started up again.

  12. Manual Tuning Options

    Hey All, I am picking up my Supra within a month or so and it happens to be a manual transmission. With it also being a 24' model I am aware the ECU will be locked and I am limited on tuning options without spending a pretty penny. (To my knowledge) Ive heard mixed reviews about the JB4...

  13. Used Supra Buying Guide

    Mine is a 2020 (bought new) and have not done the recall on purpose.. so it's fully flashable out of the gate for the next owner when it comes time to sell..it will be a while though. I run JB4 (plenty of power for me) and Eventuri intake for decoration. I left the exhaust alone since it...

  14. Kenji Garage DP vs Active Autowerke DP

    This sold me. Kenji it is.

  15. Can someone review these jb4 map 5 logs for me

    Sorry, I missed this. Logs look good, even Map 5 is clean. You should take a full log from 2500 to redline though. Maybe do a quick check on your charge pipe connection though. there is possibly a small boost leak. WGDC is higher than I would expect it to be at this boost level.

  16. Went to the track tonight, much was learned…

    Decided before the weather get god awful here in Fl I’d try to get to the track with the new tune and see how things went. In the process learned a few things. 1. I bumped up to e40, I thought this will be ok I was e30 before whats a little more ethanol… Current tune did NOT like that at all...

  17. Central FL (Polk/Lakeland) Shop?

    Hi guys. Just bought my '22 3.0 about a month ago. It already has an exhaust. I don't plan to do too much more power wise. Just a catless downpipe and jb4. Can anyone recommend some decent shops in the Lakeland or even Tampa area? I know I can google it, but I prefer word of mouth from other...

  18. Tried out map 4 with the jb4 on e30, here are the logs…

    I did 477/565 on e40, JB4/Backend Flash/Exhaust/Intake. Razorlabs just did some more tweaks timing is up a bit more now, fueling is better now probably added a few more HP the best part is the cars power curve looks like a table top over 400rwhp from just over 3500 to 6500

  19. Valvetronic Servimotor needs replacing?

    I think this error code is referring to the motor in the cylinder head that controls the intermediate swing cam, not the exhaust flap.

  20. New (and old) SupraMKV members say hello!
