Hey guys. I have the Stage IV UTEC base map that I used as a base. I retarded the timing a couple degrees as I run good ol 91-92 octane in Nebraska. The boost map is fine, 17.5psi to redline, timing is fine and I'm running the stock fuel map since my EGT gauge/wideband is not installed yet. While I was racing tonight everything is fine in gears 1-3 but in 4th at WOT it would knock. Any ideas as to what would be causing this?? Any way to fix it?

do you have any logs?? kinda tough to suggest anything if we can't see exactly what's happening.
