Supercharger or new HCI?

Got dynoed yesterday...

So after about 10 pulls it put down 375rwhp and 400rwtq. I was hoping for a bit more, and he said there was about 30-40 more in it, but I wanted a safe tune so we called it a day. My main concern is this, I have a series two PMS and the car shows lean until 4000rpm. He told me the series 2 PMS doesn't take over until 4k so there is nothing I can do about the lean condition up until 4k (the $500 upgrade to the PMS will allow tuning lower in rpm he said). If thats the case, that sucks. I have a 255lph in tank, t-rex in line, 42lb inj, pmas 77mm for 42s, crane ign, crane coil, new plugs gapped tight (the spark was blowing out), and fresh wires. Anyone have any insight into this? I will post the dyno sheet later today.

Any help would be great as I am pretty sure I am getting some pinging between 3-4k when I jump on it.

Yeah those numbers make perfect sense for a safe tune.

How many psi is your supercharger kit? I would have expected about 385rwhp/385rwtq with an 8psi kit so if that's what you've got, you're doing pretty well.
A safe conservative tune would be an AFR in the 11's at WOT and just enough timing to avoid pinging on 87 octane at sea level.
