X3 on being LEAN & oil pressure.
A general rule of thumb is 10PSI per 1,000rpm. i.e. 5,000=50PSI. Was oil level correct?
I had trouble with lean situation my recent dyno session. Did you pull plugs ? Dyno sheet showed rich..plugs showed borderline LEAN. You can't play with timing much with a lean condition. when I got close on mixture we increased timing 2* (31 total) and found 18 more HP and moved HP band UP !!
I'm sure there is more in yours as well but watch OP & lean condition..
