The 109... questions

[Winger]

Hey guys. What am i doing wrong? Everytime i seem to screw the engine for no obvious reason. Oil and watertemps are fine and i always try and keep her good below 2500 revs.
I somewhere read that pulling up the throttle too fast can damage the engine. Ist that correct? Could that be it?
Or am i missing any other settingg that must be handeled with complex engine management other than revs, oil and water temps and if the gear is up or down. What is the deal with the ATA pressure? Is there a way to control it? Whats the perfect value? Where is ATAs critical area beginning?
Would be cool if someone could give me something like a list of thigs to do and things not to do in order to get optimal performance out of the 109. I never seem to get her faster than 400 kph in a level flight. Isnt she supposed to make much more?

Thanks!
