defo consider a remap - the N52 seems to be one of the few NA engines which respond well to a map. I had my 2.5i (177bhp) mapped to 200 bhp! Which I was astonished at.
Actually from what I can make out the facelift 2.5i is the only E85 engine that does respond well to a remap. Probably because the 2.5Si was pretty much the same engine but rated at 218bhp - I'm guessing because of BMWs original mapping!
As Marlon said you might get 15 bhp on a 3.0Si, but if they are required then why not?
Z4 3.0Si Sport - Coupe for added stiffness!
Current - Montego Blue, Pearl Grey & 108Ms. Cruise, Storage and pdc. 325ti Sport as a DD.
