Find a nice road where you can do 4th gear pull. If you have to then do a third gear pull.

Log RPM, TPS, TIMING, and O2bank1

Log WOT from 3k to 7k.

Start low 15psi and move your way up. Log for a nice advance in timing and make sure there are no dips/knock. Watch your O2's and also watch your egt's.

If you really want to make it easy on yourself just save up and buy a Wideband w/logging capability. Replace your rear O2 and tune for 11.5:1 AFR and a nice timing advance. I've made high 2XX's to low 3XX's with a wideband.
