Added a slightly smaller upper pulley since then and seems to be around 16.5 psi. Been thinking about heads but, I’m having trouble finding traction as it is on the road course at my level.
Ive been tempted to fillet open the Magnaflow muffler and put a true X pipe in there. The packaging is hard to beat. I would do it so I could swap the MBRP resonators out on quieter track days.

Yeah your motor is the restriction, not the muffler IMO. I’m at about the same boost level but 200 WHP higher, so that’s a motor efficiency difference. Blowers are comparable so no issues there. Cam and heads would probably drop 3-4 psi off your boost number. Are you catless at the track?
