Alright, so when my car is fully warmed up and idling, my pocket logger will read 5 deg. timing and sit there solid. I know its supposed to read around 8-10 on a logger, probably more since I am at around 7200ft elevation.

My timing curve on WOT is alright; I max out at around 18 deg advance on 20psi with no knock. The only reason I notice this as a problem is because the car does not feel any faster on 20psi than it did on 15 after I put in my injectors and tuned them. I checked my cam pulleys, and the lines match up perfectly. Any ideas why it'd be reading that low on idle? And is that max timing a bit low as well? Thanks guys.
 
Your timing should bounce around at idle. The ECU raises and lowers timing to keep the the idle steady at 750 rpms.

Sounds like pin 52 to the ECU may be grounded somehow.
Pin 52 = Ignition Timing Adjustment for 95-96.

Check your base timing with a timing light, with your logger cable plugged in and unplugged.
Your logger cable may be grounding the Timing Adj. wire. I'm not sure how 98s are wired up.

Edit:
Reread your thread and you have higher timing at WOT so Timing Adj. Pin not grounded.
I would check Base Timing, if possible. And if Air Temp, Baro sensors, etc are reading correct.
