My fuel flow, at 65% power, for my 200 HP T-Arrow is about 12 gph , but at
65%
power I cruise at 150 KTAS (or better - I plan for 150 tho) and can fly
non-stop
for 700 NM - But this is also flying at 8000-13000 ft.

First of all, 12 gph for 130 hp sounds to me like a lot of gas. I can get
the fuel flow on my 270 hp engine down to 12 gph at around the same power
setting (60-65%). You might want to double-check your engine gauges.

Secondly, turbocharging isn't a fair comparison (you as much said this),
since you get to enjoy full power operations at the higher altitudes where
true airspeed increases.
