How are modded 240s tuned? I never see a dyno sheet in the for sale section.

maybe (obviously) you speak from 0 experience,

If you have a dyno sheet and it has a phone number on it you call and ask for a copy of the file, any reputable shop will provide it with the OP's permission, the file contains all the info you need to verify that no scaling or correction factors are included and the viewing software is usually avail free on the web... the file also contains all logged parameters such as A/F and boost.

You show your lack of actual knowledge every time you post maybe you should lurk more and troll less, all I see from you is misinformation and thought processes that go off half-cocked.
