Back to your question. I would add the 178m pulley since InMotion has reliable tunes for it. You may have that tune already.
Ill check out those afr's some time this week. going to WV to pick up my daughter for a cpl weeks so when she isnt draging me from here to there :P .. it was a custome tune from inmotion so yea im prity sure its for the 178.. he told me thay would give me a free reflash though if wanted.. but so far 178 is the way to go if i keep the same tune then *nods* has there been any better reports on the other pulleys like the 181/185 and so on
