My upgrades are straight pipe FMC and intake and blitz blow off. Any help is much appreciated. Thank u
First, sorry for the delayed response. If your Supra is still having the problem, it sounds like a boost leak to a blown intercooler coupling for example. A small tear or partially-slipped clamp on the back-side would be hard to see, and would only leak during hard boost - which would throw the ecu into limp mode when boosting...but could seem to behave somewhat normally when not boosting.

To troubleshoot, just pressurize your entire charge-air system to about 20psi. You'll hear the leak.

Displacement is no replacement for boost.
Life begins at 30psi.

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.
