Hi Tony,

I'm confused too when you says 29" MAP gives you 15GPH. It's the
throttle/mixture/prop setting combination that will determine what fuel flow you
get, instead of just throttle. You could go to 32", while keeping 15GPH which
should give even lower temps (not soo low because the intake air comes hotter as
you increase MAP due to the turbos running faster, there's only so much cooling
the intercoolers can do).
