As you guys now, a few of M8 forum member already been using RaceChip GTS Black on their M8 with a great result.
I have been having a great feedback on RaceChip since I start offering it in 2015.
Currently, I don't have a dyno sheet of F91/F92/F93 M8 itself, but the number is very close to F90 M5.
So, here I will share the dyno sheet, video, and installation instruction from F90 M5.
I will update it once I have the dyno sheet for F91/F92/F93 M8 itself.
Installation wise will be the same as F90 M5 since the engine layout is identical between the two chassis.
Enjoy and feel free to ask any question or PM me for quote.
Their Dyno result.
Edit: Here is the installation instruction in PDF form and Video.
