NOLA: Bad news...

You're only getting 7.5 psi peak boost!

Worse news...

Your boost doesn't hold steady after it peaks. It falls off to only about 6.7 psi boost near red line.


I suspect that your wastegate boost sensing line is still hooked up in the stage 1 configuration (connected directly to the turbo outlet). For stage 2, it's supposed to be teed into a vacuum line that connects to the intake manifold (per Prodigy's instructions).
