AP1 Comptech SC on 04 AP2
Little update, I am seeing the following....
Idle: 14.7 AFR
Cruise: 14-16 AFR
Full Throttle:
2k RPM - 6k, 12 AFR
6k - 6200 rpm 11AFR (Spike)
6200 - 8000rpm......... 13.1
I am very happy with it now. Would like to leave it as is. I am running 7psi.
Should I keep adjusting AFR till 12.5 or keep it at 13.1?

2K-6K...11s
6K-6200: 13.5
6200-8700: 11.5
8700+: 10.8
I need to adjust it somewhat to get the top end a little higher, as I'm losing power there, but my vacuum tank got chewed up so I'm driving around with a CEL till I get that from Majestic.
I think high 12s is just too lean IMO.
When it gets cooler out or you run it at night, it could go above that.
Bottomed out and now it's 13.8. Sigh
EDIT: So full bottom it seemed to run weird and sloppy not to mention AFR up top was 13.8. I backed off 1.25 of a turn back up and AFR is back down to 13.1 bit. So weird. Seems to be running strong but I am concerned at this point.
Step colder plugs and boost gauge will he going in next weekend.

I monitored my IATs via Torque on my Android phone via bluetooth OBD2 scanner. The reason I got it was to read codes, but it has some monitoring built in, too.
I am in the low 50C range when moving, but it can creep up over 70C (158F) sitting with the motor running.

After some research I came up with the following... Since I cant go below 13.1 AFR in the top end I should check the following...
1) Check Voltage on the Fuel Pump
2) Buy a fuel pressure gauge and check fuel pressure.
Anything ales? My WALBRO pump makes bunch if whine noises and primes really loud. But people say it's normal.
