I see 25gal/hr on take-off. 

That seems low but I am not a Bravo driver.  Savvy recommends 26.2 - 26.7gph FF for full power takeoff in my TSIO-360 (252 Encore) to keep everything cool on the way up.

Question for all Bravo owners:How many gph is your full power fuel flow on take-off?

Now, I'm curious @LANCECASPER.  What are you experiencing and are you concerned for some reason?  Also, did you recently install a new monitor?  I did and I have been trying to tweak the K factor setting to get the fuel flow just right....

Just checked a bunch of flights in Savvy... 30.5.. going down to 30 at 1000' where you pull back to 34/2400.

Where do you see the gph at?  I have Fuel Pressure on my Moritz gauge.  I can pull up gph on my JPI700 but never pay attention to the gph on take-off.

Cruise climb 34/2400 is 24 gph
Shadin and TXI Eis match

Mine is too low so we are checking a few things.

Between 28.6 and 30.2 for me (easily extracted from EzTrends "Data Trends" with option "Report Data Type" = Max. If you have an IAT probe then this is also an easy way to check the max MP setting as required by Lycoming curve 13495-A)

Engine POH curve 13491 specifies mixture strength 0.60lbs/BHP-Hr which would be ~27GPH - personally I would be happy with that to +10% which is just about where I'm at
