My RB26DETT runs a D jetro power FC everything else is stock apart from the fuel pump. It runs 1bar (14psi) of boost.
When I drive (cruise) above 4000rpm my engine misfires and turbos chug. This only happens when I hold the throttle constant and not during accelleration or decellaration.
It does this at all rpm settings above 4000rpm when the throttle is held constant.
Any suggestions on what may be causing this?
My thoughts are fuel pressure problems, or maybe spark being blown out by the boost but unlikely as is ok when rpm rising.
Maybe MAP sensor?
