I would love to go fast in reverse for some 180 turns. :)

I saw that post... pretty funny. I'm glad the MR guys got that issue resolved.

Those are SST tunes. Playing around with Throttle Position Sensor..
RA reverse gear is 1st & 3rd gear working together.
SST TCU control & limit the output,

RA reverse.
Evo X MR & SE 1st gear.

Now better response in 1st Gear on Evo X MR & SE.
Now better response in Reverse gear on RA.

To put it simpler... the Ralliart doesn't have any limits to WOT in first gear, whereas the EvoX MR does. They were able to modify the sensor that limits the throttle position (TPS) on the MR during first gear to help protect the transmission, I guess.

What MTZL is referring to... they were also able to modify the TPS for Reverse as well. Zoom-zoom right into a wall going backwards if you're not careful.
