After a lot of delay from out-of-town work, patio rebuilding and "cut & 
paste" stainless steel work on the heat shield, I can finally report 
that the new turbo T04 installation flies. The one issue I had on the 
0.9 local flight was an erroneous EGT reading. I installed a new sensor 
and it's reading very low - 300F.

Boost still has a tendency to run away above 44 MAP. I've been gradually 
tweaking the boost controller toward minus on each ground run, but the 
wastegate doesn't seem to be doing anything. So far I have about 1.5 
hours ground running on the turbo. I held her at 40 MAP for take off 
which was more than enough to get me 80kts less than half way down the 
3000' funway.

Take off acceleration seems to be a little less than with the stock 
turbo. There's no sign of oil or soot on the prop and the oil (recently 
changed) is staying "oil color". With all the stock turbos the oil went 
black within an hour of running.

Perhaps now, finally, the fun begins.....
