Is torque punch and torque reduction even necessary to play around with? I would think the ots flash from XHP is set to where they think is the best?
It is set to where XHP thinks is best but that does not work for everyone depending on power levels, and tune.
Some people have had to really turn Tq punch down to have it drive the way they want it to. Best to see what you want out of if and make one change at a time and test.

I've still got all the hardware ready to got M3 GTS via the GWS mod. However I don't want to change the diff. So the only way I can see to keep the original 2.56 FD is to go xHP. Has anyone flashed xHP on with no maps then done the GWS mod to allow you to keep the 2.56 FD ratio?

edit: Thinking about this more it doesn't make sense as flashing the GTS via Winkfp will erase xHP I assume so back to needing a diff to match better with the ratio the GTS map is expecting.

There is another way and will likely be known about more broadly soon ;)
