Dave,
My 01 Calif. Special had the pc3 and dyno. Then Todd Egan (Guzzitech.com) had me switch around some tune #'s he thought were too rich........ bottom line, it ran great all the time and the numbers I changed were fairly dramatic. Not sure you need the dyno. Also pre-dyno they told me to bring a stock filter. Huh? I had the K&N already!
They said that on m/c's it doesn't make that much difference and that stock filters often work better! Turned out running both filters came out about even.
P.s. I also use to own a 74' eldorado police special.
Got 1st place each of the two years I rode to the M.G. rally in Prescott, AZ. with my 01.. It's for sale now, $6695. My riding brain can only handle one bike at a time.
