Boost creep with the new setup!help i want to track it!

[A2TDI]

setup

built aba bottomend (2008cc)
20v head ported with all springs, retainers and ferrea valves, and QED purple cams
turbo: HX40 with BEP .70 ar ex housing
precision 46mm wastegate (18 lb spring)
CTS cast 4 into 1 t3 exhaust manifold

this thing creeps like a MOFO! it spikes to 25 lbs instantly then raises to 35psi before 7000rpm and there is no boost controller and i have changed the boost source from being in the manifold to right at the compressor. I want to eventually have the car tuned at 30 psi but right now if i keep my foot into it it doesnt ever seem to stop climbing in boost. I had a tial 38mm gate on it and it was creep so i said hey ill buy a new much larger gate and my problems will be solved! I was wrong... A couple things i didnt mention is its running on 94 octane, water meth and the engine endures the constant strain of a built 3 spd auto..

What was changed from the old setup?

Make sure you have the extra side port plugged on the Precision WG, those get forgotten all the time.

the old setup was the same. same manifolds,engine,cams everything the same except i had the smaller turbo the hx35 and the tial 38..so this year the only thing i changed was the turbo. after i realized it was creeping i through on the larger gate and same thing happened. poor designed manifold? and I just checked right now and yes i blocked of the second lower port.

Fire ring insalled on the gate? I've seen people forget them.

How long is the your wastegate dump pipe? Is it straight or are there many bends?
