Boost kicks in at 4K rpm's???...

I'm a little confused.
I'm used to the "instant-on" of the turbo kicking in with my '98 9000CSE. I barely have to give it any gas, and I'm basically pinned into the seat!
I bought the '93 900TC 2 weeks ago, and have noticed that the boost gauge always stays in the yellow. Now, I know this means base-boost, and I know that there are some things I can look at to correct this problem.
What I don't understand is that I disconnected the "W" hose from the APC solenoid, and drove the car VERY CAREFULLY. Well, I don't think I needed to be so gentle since the real boost didn't start to kick in until the tach reached 4K rpm's. I had to get the car moving pretty fast for it to have gotten to this point. Is this when the boost is supposed to come alive? I thought boost should kick in much earlier than that. Am I expecting more out of this turbo (since I'm used to my 9000) than I'm gonna get?
I actually thought the car was stronger with the hose attached normally to the APC solenoid, even though the gauge always reads yellow.
BTW: what turbo designation does this 900TC have?
