Boost pressure (actually MAP), along with other useful readings such as IAT is available in the OBD2 connector. No need to attach boost gauge.

I understand what your saying This is why im only investigating at the moment.

Also thanks for the information about the different boost readings i could get

Yes i would get a before and after reading for boost should i go ahead with this modification.

Also 11 psi rings a bell.

Interesting, would also be more accurate than a gauge !
