I was curious... I am planning on installing my BMS Meth Kit in the coming weeks, as well as a FMIC. My question is, I have been reading up on stacking the Cobb and JB4 together; with my current set up on my 335i (See Below) would it be necessary to upgrade to a G5 Board if I wanted to run these together, or can I just use the G4 board and be ok?

I will not be consistently mixing E85 in my car due to there not being a station with access to it for 20 miles. So if I will just be running 91 octane with the Meth Kit, the G4 board should be sufficient enough for me to use towards the BMS Meth Kit right?

Thanks!
