Anyone having issues in HPT after 3.0 upgrade?

Updated my HPT to 3.0 a couple months ago and have had nothing but problems since. I almost blew my engine when my tune stopped reading my MAP sensor above 105 kPA. I imported the tune from the PCM and flashed directly back onto it and it fixed it.
My voltage offsets on my wide band formula was way off. I went from adding 9.5 volts to adding 11.5.
Now, my anti-lag doesn't work. I use a relay to disconnect the IAT sensor, and then pull 25 degrees of timing from the farthest left column of IAT timing table. Has always worked. Timing drops and then bang bang, I can build 8 PSI in neutral.
Now, the only thing that happens when I disconnect the IAT is the car stumbles and dies. If I mash the gas it will stay running, but it doesn't seem to be pulling any timing.
