more like 150-160psi for the comp figures mate... no way u get those figures on valver engine.

i Know this is really old thread but its the only one i can find that has the same problem as me!! was there ever an answer to the problem of restrictive high revs??
cheers
Looks like fuel pressure due to failing pump.
when mine did this it was due to the cold air feed i had rigged up crushing in on itself and restricting the air flow into the engine, so check all you induction setup for blockages/knackered filters etc
if those compression results are right i.e. over 200 psi then the valve timing is wrong, should have been checked first.
