New 2018 Nissan 370Z Nismo

The UpRev tune might be locked. If that’s the case then the shop isn’t actually doing anything but uploading the tune and verifying power on the dyno. You could actually upload the tune yourself. If the tune isn’t locked then the shop is just using UpRev as a starting point so they don’t have to build the entire file from scratch. VQs are tricky to tune and I wouldn’t want just anyone building the tune from scratch.

On a topic listed above, the location of the MAFs is the primary problem with the Stillen kit. They are preSCer which basically means the ECU has no clue what temperature air it is receiving.

You were right on target! The file was locked from stillen and you can’t change the values or improve on the stillen canned tune. On June the 7th a tune shop that is approved by Uprev in Portland will get rid of the stillen can tune and make one from scratch. The stillen tune is running good so far.
