I think the tank is to far away from the engine. It might be fine when the plane is level but with the nose up I think it will have a hard time to draw fuel, and will lean out too much.
A custom made tank right behind the firewall would be better for the engine.

To me the TT07 is very sensitive to the tank placement. Mine ran fine on the bench but in the air I had a few lean runs and that was it...
