Engine bogging down with any swift throttle change

[Rotary Evolution]

the lower ports work but the closer the port is to the intake port in the engine the more resonance the signal will get. you can get by in most cases running an unfiltered line to the throttle body ports but the ones off the LIM should have an orifice in each line to each device otherwise they will 'flutter' in the readings.

i dislike teeing off more critical components like the map and pressure sensors. boost gauge and blowoff valve are less significant. albeit less significant to tee off the pressure sensor on a AFM/MAF based system, it is still used for engine timing calculations, so if a line off that tee ever does break it will advance timing to the ambient reading table which could lead to engine damage although i have never had it happen.
