Failed MAP sensor?

[dkw_dude]

Yes, I am running 7A cams. All I did was make an extension harness to go from the front to the rear by the dizzy everything has been working just fine for about 3k miles unless the plastic gear on the dizzy spun slightly... but even then it only cuts out at certain boost levels. I can rev the car to redline as long as I don't exceed ~15psi

I'm just thinking this:
7A cams makes the engine more efficient and more air goes through maf than on standard cams. At max boost/high rpm the maf value will be outside the map (presuming your map is for standard cams) and ecu will then reset.

Completely wrong sorry.

The problem is probably spark not going where it should. Check the plugs.

Ok. But am I wrong in thinking that there is some sort of limit where the airflow is so much more than what the engine is mapped for, causing the ecu to take some kind of action?
Sorry for slight o.t.

There is enough information on this forum to read about it, sorry, I am not going to spoonfeed you.
If he was hitting MAF limiter he would have a code stored and limp mode. He doesn't, so forget the ECU, the MAF or "too much air".
