I thought about it some, and decided to force the ECU into open loop at 0 psi by using the e01 to output 5V to the TPS when mani pressure reaches 0 psi. I think the ECU sees a rock steady max MAP voltage as unusual so it cuts fuel (maybe the programmers suspected a huge vac leak would be occurring when the TPS is showing only partial throttle and the MAP pressure is close to atmospheric). When you think about it, near atmospheric pressure should only be seen in a NT setup when WOT. Thus making the ECU sense WOT anytime the mani sees 0 psi should be closer to what it would expect.
