What will happen...

I don't think that is what he is asking, the stock pcm in our cars "stops" at 7k rpms. He is wanting to know what happens after you rev it past where the pcm can go.

I dont think it would be a good Idea to try and rev the pcm further that its max.

It’s all a matter of costs. If I go with the "big" cam, my shift point will be 7500RPM. If the stock PCM can't handle that, then I am looking at $2500 for an aftermarket PCM. That’s a third of my entire build! I can put in a smaller cam if necessary now, shift at 7k and up the cam for and PCM at a later date. But if the stock PCM can be tricked to do so, then I will go with the bigger cam. I just need a definitive answer.

Huh ?
YMMV, of course
And to the OP, I'm not sure exactly where the stock ECM stops or even what happens if you try to go past it. I will ask a friend of mine, how he manipulated his ECM and how far it can be taken.

I have that problem with my car.The cam is suposed to make power to 8k and I can only spin it to 7k.I need to start saving money for a BS3 so I can atleast goto 7700 or so and use all that power I am leaving on the table and maybe trade my 410` in for some 456`s
