Scott, start a new thread and there are plenty of 535i experts on the forum, majority of them much more knowledgable than myself.
I have a 2011 F10 N55 PWG with:
JB4 w/ Bluetooth
Wagner intercooler
BMS intake
ER chargepipe
ER castless downpipe
Muffler delete with 3.5" tips
Mixing E85 with 93
I been very happy with the performance increases and my F10 feels like a race car. Check out AZ's recent progress hitting 141mph with 21 psi peak.
