Just flashed today with the xHP stage 3 tcu tune to my 19 m5 comp which currently only has a BM3 OTS stage 1 93 tune (plan to go stage 2 soon). Can tell its stronger shifting and quicker, as well as LC seems stronger. I have no clue as to how much performance difference it will make with 1/4 mile or 0-60 or 60' times yet, in due time. Weather blows right now. Need winter here in fl big time.

I used the same cable as i flashed with my BM3, a little tricky getting it up and running, seems the app doesn't like my windows. Would like to get the wifi or blue tooth dongle thing instead so I can adjust with my phone back and for some of those settings since its going to take a lot of trail and error unless we all share what is best etc..

The other options this app has look like fun to mess with but I didn't especially with LC torque settings. One thing I've been confused at even from the get go doing dragy's with my m5 is what is ideal shift points for fastest et / mph?
