I'm swapping from a 305 TBI to a 350 TPI (speed density). If I have the EGR disabled through custom tuning, What exactly do I need to do with the vaccum connections and such? Also I was wanting to ditch the smog pump too. I have a Magnaflow High Flow Cat., do I plug up the air line?? I have a set of Mr/ Gasket headers for a tpi car with a O2 sensor bung and a threaded hole (for an air line maybe)?? Any thoughts or ideas?
