OP, pls. let us know what you hear back on that.

Enjoy it!
Dinan runs rich but his AFRs are a bit off, it should stay around 11:1-12:1 in the high RPM range. His fuel pump may be failing which could explain the dip and strange AFRs.

OP are you experiencing MPG loss? A failing fuel pump does not atomize fuel correctly which reduces MPG and HP.
