That's only with an oem tranny beefed up with aftermarket parts (eg. Soundperformance, Boostlogic, etc.). Bone-stock, the oem mkiv tt auto tranny can only relaibly handle about 525rwhp or so...depending on how hard it's driven and how much rubber is on the back tires (in other words, don't do donuts with 12" wide slicks, 525rwhp, and a bone-stock auto tranny).

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.
