I'm assuming you have checked for leaks already... Check silicone clamp areas and also bolts on the intake manifold where you touched or removed.

Bigger IM = More space to fill
More space + same turbo pushing the same amount of air = More time to generate the same PSI
This is assuming there are no leaks

Re: i gotts turbo lag
Oh and I didn't look closely enough, you really should be running a 3" downpipe... 10PSi+ is 3"+. Might help some. And what fuel management system are you using? What tuning? All these facts play in this equation.
