After doing some more testing, fp tracks boost pretty good up to about 15 psi boost then slows to a little less than 1:1. Frankly, it is a little hard to watch gauges that closely but it appears to be a little less than 1:1 up in the 60 psi fp range. How much should I worry about that as long as KR is low or zero? What other parameters are critical in this range? Max boost looks to be about 18 with fp about 16 or so above line off setting.
Thanks,
Charles
