Buly,
With your engine, removing the turbo makes sense.  You can probably get enough 
horsepower with the NA setup.

In my case, with a lower compression turbo engine, I'll have to stick with the 
turbo to get enough power.

I have about 42 hours now on my already used stock turbo, with no problems.  I 
have been nursing it along though, and don't exceed 5-6 lbs of boost on 
takeoff, and usually fly at 0-2 lbs of boost max.  Sometimes I cruise around 
at less power than that to conserve fuel, if I'm just flying around.

I do think that the stock turbo is going to fail, and I have all  of the parts 
to convert to a T04 turbo, which appears to be the best long term turbo 
solution.  

As I recall, when Dave had his turbo trouble, he gutted the turbo, and still 
used his same exhaust system.  Is that what you did, or did you redo your 
exhaust ?
