Hmmm.. Progress, but I would probably still go JB4/downpipe/ethanol and a custom JB4 tune until you can get a custom tune done and unlocked ECU. Not sure how I feel about mailing my ECU to Europe to get an OTS tune. Lot's of risks there.

1 person on the forum, lost his ECU thru mail within US, can't imagine shipping overseas.

Wait what, so they’re not unlock able? RK Tunes bullshitting?
Well, sorta. Based on what Visconti is saying there, it appears that RK can generate signatures for modified software.

Any OTS tune is a non-started for me. I can't even imagine doing something like that and expecting good things long term.

If it was specifically designed for the Supra it could still be a nice upgrade if the tuner is competent. Think APR on a VW. But yeah getting the max potential with specific bolt ons and fuel will require a custom tune.
