I've got mine scheduled in a couple weeks so glad to see the feedback.

As long as it's not disabling any codes from the safety or smog system sensors (cat efficiency, O2 sensor, etc.) you should be fine in MA. I "know people" who ran cars with basic tunes for a while without any issues.


I have a separate question - does Lexus have a way of determining if the ECU has been flashed for the purposes of rejecting warranty claims?
