I also installed the Dynojet map on my PCIII on my 1500 Classic. I did lean out the idle portion a bit cause it ran too rich at cold idle. Mileage dropped a couple MPGs compared to stock pipes. I also run stock intake but could "feel" the increased response. I have run this map long enough to believe it is close to optimal but every once in a while I consider going to the dyno. I don't care about the top end HP, but it would be neat to see the torque curve.
My map from Dynojet actually reduces the fuel amount compared to the ECU at lower engine speeds and large throttle openings. It's just a function of the pipe dynamics. Mine are not an optimal pipe design...I have them for looks and sound anyway!
