Lol the head might be rated for 20k rpm but not the bottom end, dont rev any higher than 5000-5200 rpm. thats where the power band stops anyway.

You said it cuts out after 10psi of boost, so maybe there is a fuel cut?

Well if he put the stock fuel pump back in then it would make sense on why the car cuts out. I believe the stock fuel pump can only deliver enough fuel for under 12psi.
