This question is regarding map connection on gm 7.4. Early 90's they connected to a source on the throttle body, 93 they had it connected to #8 runner and 94 they connected to both #8 and #7 runners. I expect the 8&7 were to smooth the pulse but I was wondering why they moved from the throttle body. My after market intake only has an outlet on #8 and the pulse is really jumpy. To the point I thought maybe there was a problem with the motor. I connected to a source on the throttle body and the gauge is super steady but it doesn't idle as well. I haven't done a ve redo but just wondered if there was a reason I am missing why it was moved from throttle body to runner.
