Referring to the start of the thread and the varying AMM signal, is there any way to check that it really is intake pulses you are seeing? And not interference from ignition leads, etc?
It seems impressive that the intake pulse can still be measured after passing out past the throttle, through the intercooler and most importantly out through your turbo (especially on the WOT run where the turbo would be spinning at full speed).
