My money is on tuning.

I have personally seen lag dissapear from both EFI and CIS engines through meticulous tuning. When you get the cam timing, ignition timing and the A/F ratios perfect the whole world changes.

Another moving target, there are turbos designed specifically for EFI applications and turbos designed specifically for CIS. Your K27HF turbo probably does not have the same characteristics now that you run EFI. Stephen is an expert in that area.
