Check your manifold to see if it is cracked (Most likely it wont be cracked, unless you still have the stock 1g manifold). Also check the four bolts on top of the manifold that holds onto the turbo and make sure they are tight. If they are tight, check the metal gasket that lays in between the manifold and the turbo. My guess that there is a leak somewhere around there, causing air to escape and not spinning the turbine wheel like it should, and causing slow boost build.

I would also consider looking at the wastegate flapper to see if their is a crack on the housing (i highly doubt thier is a crack though, but just incase) causing air to go pass the wastegate and not spinning the turbine wheel like it should.

Check also to see that your wastegate is tight. Not moving freely. Make sure the wastegate flapper is closing all the way.

My .02 cents.
Mods are Big 16G turbo, Blitz BOV, 3" turbo back exhaust, S-AFCII, Greddy Electronic Boost Controller. I have not had the car long and am not sure if I have any fuel upgrade mods, I need to do a little research into the injectors.

Once the boost builds it does not sputter at all, the boost holds really well and the car pulls.

Thanks for all of your advice here. I will spend a night during the week investigating everything you guys have pointed out.
