4000 RPM is where the safeties start kicking in ... perhaps you have an
intermittent signal to the ECU ... perhaps the boost pressure is a bit too
high (or transducer is flaky) ... perhaps the dizzy is adjusted to the end
of the range for catching the TDC pin.  

I'm assuming we're talking about a WX/MAC-02 ... please post what mods you
have ...

I'm at a loss and any possible sources for culprits would be very
appreciated.....................smooth to 4000 revs then acceleration gets
'bumpy,' doesn't happen in 1st or 2nd..................just had a new clutch
put in, and the clutch master cylinder replaced but this was happening prior
to that work...................stumped and getting frustrated.

Thanks, Donnie
