I finally got things together except one last issue which causes major grief. I have a brand new Harrop ITB, the drive by wire version, on that track LS7 which causes reduced engine power (P1516) anytime I hit more then 60% TPS.
all tables are maxxed out, I nudge P2101 TPS error values like Bill suggested but it comes up as soon as I hit WOT and let go off throttle. It doesn't seem to come on as long as I step into it, it comes on right when i get out of WOT.
that would be real show stopper for that system and not sure if this is a 06 PCM issue or if there is a workaround it.
anyway, file enclosed
