No. I am doing the same thing. Originally I was doing it so I wouldn't have to use a muffler. Tracy said as long as I didn't use it to try to attain outlandish manifold pressures, no
changes were necessary. I should say I'm not flying yet. I have been told by
others that an occasional boost for take off to, say, 35 inches is ok as well.
I did have a TO4 compressor section added to the stock turbine since the
mazda turbo was so woefully inadequate. --------------------------------------------

When
I originally bought my EC2 (possibly EC3) I had Tracy build
it for naturally aspirated. 
If I turbo normalize the engine do I need to
change the controller programming?
