Is that a 180HP parallel valve engine or a 200HP angle valve engine? If a 200HP, that fuel flow seems too low. I'd like to see 18-19gph and full power full rich.
17gph sounds right. One thing to check. Does the flow reading change with the boost pump on? In The RV-10 with the stock setup, the boost pump shows a 2-3gph increase in fuel flow, but there is actually no increase. Verify this. If you are reading 17, but only getting 15, that is likely your problem...too lean.
