Engine bogging down with any swift throttle change

Rotary Evolution · 04-26-2013, 04:46 PM

the compressor outlet doesn't show vacuum, only boost positive pressure and not the same pressure at the manifold leading into the engine so it isn't a good spot for the pressure sensor line. the sensor needs to see engine vacuum and pressure that the engine sees to accurately advance timing.

move the line to either the top or bottom front port just past the throttle body off those 3. the center port iirc goes to a port before the throttle body so isn't a good MAP source.

i highly doubt this is your problem but it is a problem that should still be addressed.
