I had the cowl off for other reasons and did the "coke bottle test" and measured
the fuel coming out of the injectors with just the electric boost pump on
and the mixure & throttle full in.

I mainly look at #3 as the rest are all lower and somewhat closer
together. I have seen #3 as high as 425 climbing full power on a warm
day. I flew recently and it seems cooler so will leave it that way for
more testing. I was just curious if those flow rates were different
enough to worry about.
