Hey guys! I have a stock F10 M5..
Not going to do much more than a new exhaust (only mufflers... MAYBE DP's down the road)
I read through all 11 pages of the BCM/S63TU tuning thread and no one answered/asked the question...
Can I run JB4 + BCM and run map2 to get the 22psi target or would I run Stage 1 and add 5psi using the datalogging cable?
And to add on, I know the clutches slip in between shifts with 22 psi and higher... is it worth the extra $650 to get the JB4 + BCM if I have to then deal with a slipping DCT during gear changes.
I understand it has all the data-logging capabilities and whatnot.. but I'm more interested in power. I know that stage 1 runs 18psi if I'm not mistaken?
Thanks guys!
Thanks!
