Default Boost pressure in cold weather

I know we should expect some boost creep/increase in boost pressure due to cold weather, but I'm wondering how much everyone else is seeing? My factory manifold pressure sensor registered 20.2psi during a run last night. Timing advance looked to climb all the way to 36deg or thereabouts, assuming I am reading the data display right. No knock correction, etc was present. Anyone seeing 2+psi of extra wind on their setups? I likey, but prefer to err on the side of caution. EGTs looked solidly below 1400degF, so no big worries there.

I have now logged codes: P0301(twice), P0302 and P0303. All misfire codes, all related to the lightened flywheel currently in the car. I need to find a way to turn this damn CEL off, as it's getting annoying.

Billy, how'd you do it again?

Thanks bud. This misfire code is a pain the ass. I hope they find a way to turn the damn code off permanently with EcuTek.

i was talking with one of the mechs from mastro and he said if you turn the ignition to "on" (dont start the car) and then turn it off after about 30 times the light will go away temporarily.

I assumed they could do this already. I know the Cobb reflash can disable any specified CEL. You want to look into this as it's possible it's supported but the folks at Mastro aren't aware of it?

Could be. There's also a way to open up the ECU to limited user changes via Delta Dash. Can you help me/us out here Kyle? If there is a way to turn off this CEL(group of CELs, actually) for good, I would very much like to do so. I would also like to turn the user options on as well.
