Just wanted to update everyone. I finally got to run the MW54 this weekend at the Greater Southwest in Waco and it ran great. No lag issues whatsoever. I did change the max temp to 850 and moved the thermal probe out to about 2.5mm and it worked fine. Engine ran great all the way through the flight. Thanks to Sara and all for the tips.
Now I just need to buy the upgraded fadec and whatever else is needed to convert it from onboard manual start to full autostart!

Too uncoordinated to work that starter button and worry about all the things going on at one time during startup. Almost fried my jet at one point not paying attention. [X(]
Other than my lack of starting skills all worked very well and I am pleased with the turbine which is especially surprising since I built it!
