I seldom exceed 4500 RPM's but last night had to accelerate to about 6000 and it began to "break up" similar to an ignition problem.

My overboost switch has been eliminated, plugs have about 30,000 mi. but wires have over 200,000 as does the cap. Anyplace else I should be looking like the power stage or the EZK unit? Boost gauge goes to about 2:30

No other engine problems,gets good gas mileage always has plenty of power. I know just don't run it up to six grand but I'd like to know I have that reserve ready if I need it.
