How many miles are on your turbos? Have you done a compression test? If I can get your mileage and compression numbers, it'll be easier to give you a good answer to your question.

16psi is safe* with fresh 93 (r+m)/2 octane fuel with the oem ecu, but no more. 17psi+ will slowly but surely damage the engine and reduce compression.

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.
