GTM stage 1 S/C - Throttle not opening fully? Or boost leak? Please help!

OK, so I disconnected the MAP sensor and the ECU throws P010A. I have no P010B, but I do have P010A,C,D. With the MAP sensor disconnected, I get full boost

OK, so I disconnected the MAP sensor and the ECU throws P010A. I have no P010B, but I do have P010A,C,D.

With the MAP sensor disconnected, I get full boost followed by crippled performance shortly after. I disabled P010A,C & D, and cleared codes, and with the MAP sensor still disconnected I get the same massive throttle lag...

So I'm fairly sure it is MAP sensor related, but it seems like my ECU probably doesn't have the MAP/MAF performance DTC's at all.

So my question is, how the F*** do I fix this!? I can't disable the DTC because my ECU doesn't have it, the DTC I do have doesn't stop the "safe mode" and leaving the MAP sensor unplugged doesn't help... So depressing!

I guess a better start would be if anyone has definitive information on how the MAP sensor's output is used by the ECU? Is it purely a safety device? I feel like there has to be a magic bullet for this problem, I just don't know what it is...
