fuel definitely needs a tidy up and boost can be a tad higher, 320rwk is what i would see from these mods everyday of the week on my dyno too.
cam timing can stay stock to achieve this, ideally end spark timing at 10-12 deg throught the run. target 12 to 11.8 at the tailpipe is usually what i run which is plenty safe.
ramp up to 16-15 psi with a slow taper off down t 13 toward 6000rpm. using open loop control
if you ramp the boost a little later instead of straight away it will shoot the power higher and give more of a flatter tq curve. on the autos this still makes the car feel great to drive, in the manuals though ramping boost later will be sluggish to drive.
