Message We stop at 13 PSI on 91 on some set ups.

Joel's set up with the large manifolds, large turbos, larger intercooler and larger short intercooler pipes allow a much cooler charge and it safe for his set up. This is only running 17 Degree's timing at the top under boost.
It also is really only 16.5 to 17 PSI through most of the range and has a small spike to 17.78 PSI.
This was all with the boost controller turned off.......this is the base boost setting on his external wastegates.
