The oem TT, in sequential mode (that's how they come stock) kick in at about 2250 rpms. The second 'stage' kicks in at about 3500 rpms.

If you upgrade to a big single turbo, then the bigger you go, the later it'll spool in the rpm band.

The oem rev limit is 6800. With an aftermarket (standalone) ecu, you can set your rev limit to whatever you want - like (for example) 7500rpms with the oem valve springs, or (again, for example) 9000+ rpms with aftermarket dual valve springs and a built bottom end.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
