I've been searching and shopping the common 540 hfm/injectors/chip upgrade, but have not read much in the way of peoples' results. What are your experiences? Worth the dough?
Any reason to do 24#s on my S50? I'm inclined to do the 21.5#s
Whats your opinion on the "best" chip?
I'll most likely go with the 3.5" hfm, 21.5# injectors, bimmerworld elbow, and TRM chip.
Thanks
