One possibility is (believe it or not) the solder leads on your oem odometer! They may need to be re-flowed. Either that or just bridge the speed sensor inpuy & output from the odo cluster harness plug. In short, if the solder leads are cracked, the oem ecu doesn't get a speed sensor signal from the transmission, which causes an artificial rev limit....usually at about 5k... This isn't a for-sure diagnosis, just one possibility...

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.
