  1. MHD+ for Supra and Gen 2 B58

    Yes. That combo is rated for 600whp on E85 per the dorch website. Stock turbo wont exceed 550. And yes you can get a little more power on E85 compared to e50. Nothing crazy though as the stock turbo becomes the bottleneck pretty quickly. I wouldnt say the $2k+ fuel upgrade is worth it over e50...

  2. MHD+ for Supra and Gen 2 B58

    While fuel upgrades can be used with OTS (you need to select them under flash options), you won't see any power gains. Don't upgrade anything without having MHD on the car, can't use the upgrades on stock tune. I would recommend DS25 hpfp and S58 injectors if you want to run E85 on stock turbo...

  3. Stock clutch - How long has/did your stock clutch last?

    4k tuned on jb4 ~450ftlb , 2k tuned on MHD at ~550ftlb no slip at all.

  4. MHD+ for Supra and Gen 2 B58

    @mustafazumit lol @djikigai yes, let me know! Still verify there are no leaks :) Looks like a bandaid tune for a boost leak. I really would expect more like 20 psi at 80% wgdc which is an appropriate amount for a pump gas map.

  5. MHD+ for Supra and Gen 2 B58

    Yeah wtf is this. 80+ wgdc on a pure 800 is not 10 psi lol Check for boost leaks then send me a PM if you want it not tuned like shit 😂

  6. New Car/Supra Owner need advice.

    Entire thread about this but tldr: downpipe + ecu unlock + MHD is more power than 99% of people need

  7. Went from Supra to Gallardo

    Yall are getting too soft since @razorlab left 😂 its just ribbing guys, of course some are gonna give you a hard time about selling the supra. Its not that serious. Congrats dude, the Gallardo is beautiful.

  8. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Seconded, looks fine but a full 3rd gear pull 2500-6500 would help with analysis

  9. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    We got him sorted out on MHD 93 custom now😉 No time wasted on OTS @steelpearl

    WTB - Kenji Catless Downpipe

    Kenji served me well before unlock. 5k+ miles no CEL

  11. M/T Supra Rev hang

    Its defined in the Gen 1 b58 tables... to enable/disable rev match@razorlab , think it exists in gen 2? I could poke around in the hex at some point.

  12. Ryan’s ‘23 A91MT Burnout - Slow Build

    Very nice, will be tough to beat but ill give it a try!😂

  13. Ryan’s ‘23 A91MT Burnout - Slow Build

    well technically you could flash stage 0, stock map with MHD still installed (and its features). OR you could straight up uninstall MHD and lock the ecu. Maybe this is a good update for those trying to pass emissions/inspection?

  14. Ryan’s ‘23 A91MT Burnout - Slow Build

    Same. Cold start off for 6 months, only had it happen the one time (within the first month). 0 times since on custom map if that makes a diff

  15. M/T Supra Rev hang

    I am fairly certain the 1-2 shift behavior is tied to anti-jerk logic in the calibration. Hopefully in my ownership and DIY tuning adventures, I will find a way to resolve it :)

  16. It's been a good run 6 years with the MKV Supra....

    I dont think anyone is trying to argue that the supra is a good daily or "all-rounder". I just prefer no compromises, so I have a roomy daily too.

  17. trash site

    Well now you know how "top" tuners are achieving 700whp+ bolt-on S58s lol. Just de-sensitize the knock sensors bro!

  18. trash site

    Anyone here have experience adjusting the Knock detection factor tables for E maps (e40-50)? I've heard they should be adjusted on high octane maps. Seems like it would be by raising the values since they are a "threshold". Any recommendations? Ive heard of other tuners just "turning them...

  19. Tuning Tools v1.0 now live!

    exactly that! very nice implementation. One more idea too, can we upload multiple logs at a time? maybe a max of 3 or 5?

  20. Logs slightly concerning

    2023 is the sweet spot in my opinion. Last major refresh, but im biased.
