Did the first tuning pass on the dyno last night, big thanks to Aaron who was the dyno operator while I tuned the car. Currently at 545whp/495wtq @ 32psi. We ran out of time so this was only fuel and open loop boost, no timing adjustments or boost PI controller tuning. There is still a bit of fuel to be pulled out up top and after ignition is properly tuned I'm confident we will easily be into the 600whp range at ~35psi. Should be able to get back on for some more tuning in the coming weeks.
The new fuel system is performing incredibly - the injectors need close to no gain because fuel pressure is so stable (a major change from before where we were compensating for dropping fuel pressure with pulse width). Started out uber rich @ around 400whp on spring pressure, all was going well until my o2 sensor stopped working suddenly. Fortunately we were able to borrow a spare and continue tuning. Didn't even touch 50% duty cycle on these monster injectors. Fuel pressure is the orange line.
Didn't get to do much boost tuning so I'll need to increase n75 DC after torque peak to get it to actually hold boost.

We also installed the Mustang motor mounts before getting on the dyno - not an easy endeavor, required a lot of cutting to get them to fit but they are performing very well - the motor barely moves at all now. I need to build a heat shield for the turbo side but they aren't really exposed to crazy heat in the C4 chassis like they are in the smaller chassis cars. My motor mounts were in BAD shape... driver's side was hanging by one bolt before Carlisle (we swapped in a good OE mount), and the passenger side was destroyed as well. Hopefully these hold up to the beating. Shifter feels nice and tight too. Filling my trans mounts with Poly and then everything should be pretty darn solid.
FWIW, I noticed no increased NVH with the poly mustang mounts, still nice and smooth.
That is exactly what people did when I said it. hehe
.............love the clean engine bay
