JB4 Big Boost

I did a little modification on my JB4 board last night and upped the boost to possibly the peak of our Turbo's. Boost peaked at 18.5psi tapered down to 15psi. The car was running extremely strong. These boost levels are not really safe on pump fuel. Maybe more realistic when running meth. I wish I was running this boost last time I was on the dyno.
