Dual fueler SURGE at WOT issue

[bluessmax]

I'm at a near witts end here. Possibly this is not a tune issue, but sure seems to be fixable via FRP PID LOOP correcting. It seems as though the ecm is seeing desired under and overshooting actual, and then over-correcting.

Does anyone have any insight? Possibly fought and conquered this issue on a lbz with dual fuelers? I was commanding 183mpa and 2804 uS.

I have not run into this issue with dual fuelers before

Thanks for any help, i sure appreciate it.:hug:

i also believe reading that a cracked check ball and/or seat from a LBZ and up cp3 can cause what your describing from the log
