Got the 3.6 pully on their tonight. No kr issues whatsoever. Still happy with 20degrees of timing. Backed it down to 18 like you guys suggested though. I remember moving the ratio and everything over when I did the swap but I'll double check tonight. Could it have anything to do with me using a 2004 comp g map sensor? I didn't move any comp g tables over because I was told they are identical. I figure that could mess up the load calculations. Only thing I can think of will be the load calculation table or the other table that's used when your maf is unplugged. Never did a map tune yet. Just maf.
