Linking to my thread in the 911 Technical forum, for turbo guys that might not visit there often.

This project is moving along. Hope to have it on the dyno within a couple weeks!

After reading your thread I got curious if Garrett has any VGT aftermarket turbos and unfortunately I couldn't find one. I'm curious to hear how the tuning goes and how you set up the VGT. Is it just RPM based?

VGT tuning is fully mapped on load and RPM, standard 3d table, with some functions like opening at cruise to reduce EGTS, closing at idle to quiet the exhaust etc.

cool project.

I always use it as an example of progress that my 4cyl cayman gts is so much faster than her older brother with 2 more cylinders.
