FYI from bm3 app note: Choosing 'OFF' removes torque limiter handling between DE and TCU (transmission computer). When XHP transmission flash is not available, you can use this option to remove your torque limit handling.

Thanks for a Sensational review mate! Cheers!

Great detailed review and video. I am having trouble just purchasing the XHP license it automatically adds the map pack when you select the Supra/ G series 8 speed. I am tuned on MHD myself and wanted to try and save the money and just get the license, but dont think that is possible anymore?

[@grumpyvetgarage]

Thanks. From what I know, you are correct and can't get the Flash License by itself for the A90 Supra.

[@momusic2407]

@grumpyvetgarage Thank you for the quick response and confirmation 👍

[@ba9092]

Great in-depth review! Thank you! Also, which Shiftmap presets are you using for D-mode and S-mode?

[@grumpyvetgarage]

Thanks! The Shiftmap presets I use are D-Mode Sportive and S-Mode Relaxed.

You should do some dragy runs with and without the xhp. Itll help people decide if its worth it or not. If its helping with ETA times

[@grumpyvetgarage]

I did numerous Dragy runs. There was no performance difference. The thing I can't seem to find is if the "ignore transmission limiters" is built into the MHD+ OTS tune or is it part of the Femto unlock to prepare for loading MHD+.

[@SSH939]

​@@grumpyvetgarageVery interesting. Xhp claims about half a second shaving off on the 1/4 and 0-60 (depending on many factors ofc) I would reach out to MHD and figure out the catch.

[@grumpyvetgarage]

I've seen claims of over 0.3 seconds gained in 0-60 with AWD cars by companies outside xHP promoting their product, but nothing from xHP directly that I can find. I reached out to MHD and they replied that, MHD+ removes transmission limiters. Basically, torque limiters being removed by xHP is now done through the DME and included with MHD+. This makes getting xHP for removal of torque limiters, launch control and torque by gear useless. Any further tuning of torque will need to be done through a custom tune with MHD in the DME.

[@SSH939]

​@@grumpyvetgarage MHD is an awesome tune if so. I would try going in stock tune then and compare xhp times.

My man, the hawk performance ceramic pads. Put them on my Lamborghini LP560 And my c6 Z06. Dust still. I saw your review before buying and don’t understand the no dust thing. Is it my black wheels on both cars making it show? I’m annoyed slightly. It’s better but there is certainly dust with both cars

[@grumpyvetgarage]

I'm getting dust from the road but not brake pads on my Supra. It is a night and day difference on my car compared to the OEM pad that is very dusty.
