Get a 3'' TU swingvalve and 3'' exhaust, no cat if you can and of course a straight through muffler. This will definitely increase spool-up.
Of course it's way laggier than a stock T2 turbo!!! You're going from a .48 stage 1 turbine wheel to a .63 stage 2 wheel!
A ported head helps spool-up a lot too, ported exhaust manifold if done right will help.
Also, you need a good intercooler, very efficient like spearco or triple stock core. The To4E wheel inside the stock cover heats things up pretty good, you need to try to keep things cool.
You are running an manual boost controller right?
