Do have an issue though. I have tried calibrating several times but to no avail. After I blip the throttle (from idle) the AFR readings are all over the place. Usually runs up to 18-20 AFR then settles back to ~14. Also the RPMS drop way low to about 400 and the car tries to die. Most of the time it recovers but sometimes not. I haven't drove it far with these settings since I don't feel I have a reliable AFR reading and the car sputters out after shifting.
I lowered my fuel pressure to about 37 psi and set my mainscale to -40. If it's just sitting I can get it to read and AFR of about 14.5. I haven't done any other low, med, high adjustments yet. Just mainscale so far.
I'm still learning tuner pro and mmcd. Not sure yet how to record and post a log. If you think that would help i'll give myself a crash course and post something up.

post your settings.
what injectors?
you need to be able to run MMCd to tune, get that running first.
Then update the Pro to version 5.03, posted above. Use the TPCU software to update the unit, its easier. Then load in my BIN. Then adjust the mainscale until the car runs ok, and start tuning by trims. Watch what O2 trim does, its will tell you if the car is rich or lean. Shoot for an O2 trim of 80, with the main trims learned down to 81.
(TPCU can be downloaded from the full throttle web site)
