would capping it at 185 or 190 be better. Also i have altered KFBLTS TO ADD EXTRA FUEL and TAGBTS and LAMFA is set to 0.828 at WOT for pre enrichment . Would stock timing be safe to use ? Of course i will do all usual logs to check egt , cf etc.
As the others say try it. But what I will say is reducing the timing down 1-2 degrees at high loads and rpms will decrease the cf's from around 6-8 down to 3ish..
