Re: best pulley?
Idle afr's are 14.7, could you get a reading of your afr's at wide open throttle thru 3rd gear? Unless the sc pulley and the 178 are still on there you should not see anything over 12's during that run. Not sure which tune he had though? Wouldn't of had Rob's tune without the mani's.
Back to your question. I would add the 178m pulley since InMotion has reliable tunes for it. You may have that tune already.
