Granted, I was still running the OEM VF39 and those don't exactly move a lot of air.

I was referring to lag. If full boost can be achieved well below 4000rpm, the turbo is effective at filling the FMIC without seeing any negative effect. Again though it depends on the turbos size. I'm not sure how small the vf39 was but the 09 and 08 WRX/STI get about 38 lbs/min turbos in the vf52 and vf48.
