Hello.
Can you tell me what the boost turbo gauge reading is supposed to be when the car is floored on an 89-non SE.

Since nobody has answered this, I'll just try to be helpful and mention:



If the boost only goes to .55 Bar there is something wrong. Could be something as "easy" as a sticking thermostat (norm = 82C, NG = 78 C.) But, there are other things that would cause the GM ECU to limit boost.




Don't know what "normal" is, exactly. :eek: Better PM Tom M.

Your dash boost gauge will also vary with altitude. Increasing with increasing altitude.

It should go to about .65 bar IIRC, not to familiar with the 89, since I have an SE. Also, all the Esprits that I have driven have been at altitude, so the boost is much higher.
