Can my K27HF be too small ?

I have rebuilt & upgraded the engine since last year and now I experience a LOT more lag than before.

Here's the background - engine before: stock 3.3 internals & CIS with Garretson intercooler, GHL headers + straight pipe.
Now, its a 3.4 with ported intake port (41.5mm) and a Bell full bay intercooler + EFI.

Good news is: there's lots more power and the intercooler works beautifully controlling temp.

Bad news is: lag is HUGE now compared to before. Just to be sure, when I say lag, its the time you punch the throttle till you see boost.

So, can this be that the turbo is too small & can't supply air fast enough? Or, where else should I look?

thanks.
