it probably is because you are using the wrong ECU... Did you ever think of that???

Unplugging the MAP make it run way rich, so its no surprise that it will start-up now.

the runners will stay open if you cap off the vac on the diaphragm, you won't even throw a check engine light.

p28 doesn't have the right timing and so on. try getting to run good on the correct ecu, or not your choice man.

hope i helped, but the p28 isn't gonna help and the rev limiter is at 7400 rpm's ? gsr peeks at 7800-7900 and the p72 rev's past it
