I searched and couldn't find anything M2/N55 specific, so please point a related post out to me if I missed it otherwise, please consider these thoughts/questions:
I have my CSF intercooler and some charge pipes on my workbench (among some other goodies) and am wondering if it's worth replacing the diverter valve while I am in there with the GFB T9357 (
http://www.gfb.com.au/products/blow-...cations-detail). Is this something that the N55 in the M2 needs upgrading? What are other's thoughts on this and/or experience with replacing it on the M2/N55?
Thanks!
