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 ?

Just came from the hangar. Managed to convert the engine to NA in 3
hours. Didn't run it since it was almost 11PM and I was missing one
plug for the cooling port for the turbo.
While doing it, I opened up John's old stock turbo that he imported
from NZ. Many of the turbine blades were missing chunks.
That convinced me that it was the right thing to do. At the moment
I'm not up-to spending another 2G's for a T4 turbo after I just spent
$2,400 for a prop. Hope I'm able to spin the prop to the static RPM
needed? The good part is I can convert it to a 2 blade fast :)
