Hey guys, not sure if there is a thread like this, if so sorry. I have a 2010 m8, was wondering if my money would be better spent upgrading to a newer sled for 2k (pry an xm) or spending 2k on a BB or a turbo on my sled? My sled has a few good upgrades already has kmod , skinz front end and has raptors all the way around, 2.6 pc, and a bunch of lite weight parts. Motor is fresh with only 600 miles on it.
