I'm looking to switch out of the GTX3076R w/ .82 to the GTX3576R w/ .63 in hopes that I'll see some better flow from 24-30psi and better low end response. Right now the turbo appears to be out of breathe at around 28psi and 510-525whp. I'm also curious how the response on the new turbine will be in both .63 and .82 configs.

I had the car back on the dyno last week in hopes to see how the turbo would perform in colder weather at 30psi vs warmer weather at 28psi and was a bit disappointed.
