Any ideas Todd or anyone else? It's Tephra V7.
Increase the values in the MAF Comp vs Coolant temp tables about 10% for temps 122 and below. There 2 of these tables, they are redundant, make sure you change both. Start there and increase as needed. This is what makes my car driveable when cold, it was doing exactly what yours is doing, except not as bad..

I did a boost leak test today starting at the intake manifold up to about 21 psi and all was good. Now that that section is good I will need to do it again but from the turbo inlet.
