So how did Joe try total timing at on your latest dyno session? How high did he go before reverting back to 32.5?
That is a huge difference to go from 37 to 32.5 for a 23* head. Timing is largely based on the efficiency of the head's combustion chamber, but you did not change heads, so I am confused.
I don't think I've seen a 23* head with such low total timing.
