    Early M12 975b MBE tuning and bolt-ons

    It's very rare when we get to see parts we've made over decade ago show up on another car. We received chassis #4 which uses a different map sensor, the very rare 975B unit and runs the Alpha N map.
    I recognized the parts, they were the first upgraded IC and piping we fabricated.

    Although the installation was home done, we did find incorrect installation of vacuum lines etc...., but vehicle was "just" running enough to be delivered.
    With 91 octane and only 15psi peak boost, we made 409whp with the smaller GT25r turbos. This is very good for an M12. Back about 12 years ago, we were at 376whp compared to what we know today and running less boost. The factory map was 262whp when received which was a poor tune from the factory.
    In comparison to an M400, we generally find 420whp at 16-17psi. with the OEM components (stock piping, IC, intakes) etc... and later spool which is due to the restrictive intakes.
