Different Fuel flows - Front and rear

[KyleTownsend]

Nick:

It sounds like the front engine is probably running excessively lean at full power settings. From what I understand, it is very important that you are getting red-line fuel flows at these power settings to insure sufficient detonation margin. I'm no expert, but I am plenty paranoid about these expensive engines. I would be reluctant to fly it at full power until I got this looked at.
