G940 Throttle problem

[ktodack]

I'm a newbe still trying to get BOB working properly. I've set throttle to go from out 0.0 to 1.04 when going from full back throttle to full forward-- corresponds to an input of -.54 to +.54.
When flying a rotel Hurricane at 6000 ft level flight with the throttle fully forward I can only get 250 mph (402 kmh). This is way below the performance stats for this aircraft. With the lower performance it's very difficult to dogfight with anyone, aircraft barely gets off the ground at takeoff with full throttle. Not using engine management.
BOB throttle settings: 0 pos. .3, 0 dead zone .05, 100 pos. .48, 100% dead zone .05, Max 100% dead zone .05. I'm assuming that with the throttle getting 1.04 out full forward the merlin should get me well over 300 mph in level flight @ 6000 ft. Help. what am I doing wrong?
