This is the FE DOHC (NA)
This is a $500 2.2 that i put back in the MX for a while.
The turbo was worn and blew about 2 months later at 18 psi.
Stock engine with 2.5 inch system and boost at the begining was at 8 psi and topping out at about 16psi.
You will notice the saw tooth in most of the runs. Thats the factory BOV leaking. Pretty much everytime over 10 psi.
Also. Please excuse the spilt scotch.
And finally here is a reprint of the best run on that above graph.. 16 psi...
