Ya, I was debating for months if I should go with the 71mm or 76mm wheel. If I had to do it all over again I would go for a gt4294R w/ a 1.44a/r turbine housing 
Hopefully i’ll have some numbers soon happy, I still have to get it tuned and would really like to do it myself. The local dyno is upgrading to a eddy braking system in the next couple weeks so i’ll be able to do steady state/load holding. I’d bring it somewhere but living in Windsor I don’t have many choices of reputable tuners or any tuners for that matter.
