Hi all, I had a brand new 06 before and now 13 WR. I found that both headpipe will start glowing when idle for a minute. In 06's, I changed to a larger # jet, by means of richer mixture, the glowing reduced much. In 13's, I tried GYTR FMF map which is +2 in the lower area, but not see any change. Do I need to increase more? Anybody tried to reduce the glowing by any mapping? Thanks!
