Got Juice?

I did forget to mention, but the TST is indicating 23.5KPSIG at WOT so my CP3 is doing fine.... no loss of pressure for poor atomization and high egt's here.

You wont blow up an S300 with "juice grips" ! Let off if boost hits 60 psi, but I doubt it will. Lots easier to mess with vice grips than adjusting the rod in place. If vice grips help, add a boost elbow or adjust the rod. I ended up putting two washers under my wastegate head to shim it since stock rods are pined and not easily adjustable. Even with two thick washers per bolt, I still have to use my wastegate controller with bleeder orifice to get boost above 30 psi. I'm pretty sure your S300 based turbo has a stiffer spring so it won't need as much finesse to make boost.

I did a little test and with no added fueling... Smarty stock, Edge 0 and MP-8 0% I could light the SPS to 36 lbs. boost. You must have a issue with the waste gate. I would do like big blue said or even take the wastegate actuator loose and put a washer between the actuator and bracket to hold more tension on the rod.
