Help with editing speeds

Hi,As some of you might know, the Captainsim F104 has a nasty bug with the FD's that enable it to easily hit M2.2 @ sea level(about 2X as fast as is correct). Unfortunatly, Cs appears to have abondoned all efforts to provide customer support for this issue and thus I have been messing with the .cfg to try to fix this to no avail. I have tried messing with the thrust and engine peramaters, but this results in an inability to hit top speed @ altitude. does anyone here know what areas i would need to play around with to correct this?thanks,David
