EGT guage/probe question

[Juggy]

ignition timing was stock....i had it SUPER advanced when i first got it running and went for a ride (no timing light)...but went back 12 or 14 degrees. I know i should be running a little extra because of G head....but im actuallly running a 2.2 swril head 3 bar cal, the car is 2.5L big valve ported G head...i think im going to get a FWDP cal in the new year.....the cals we have been getting pgm'd here in town were too lean so i think its time to step up to a vendor cal

i changed the probe, and the location!!! original was autometer probe in FM ported stock manny....now its the PLX on a TU header about an inch from the flange on #4. The PLX probe is alot thinner than the autometer if that matters at all.
