In a note dated Ramana Lagemann asks: <<Has anybody had any experience with TAP's chips for normally aspirated cars?>> No experience aside from TAP telling me there would near no perceptable gains in real world driving and that the chip should be done with a K&N filter (on my '85 4ksq)...nice of them to be honest about it-which is a good experience!
