Turbo boost ?

When I drove from South Carolina to Eglin AFB Florida last week I did 70 MPH the whole way and RPM's were @ 1900 - 2000 and my turbo boost was between 1 1/2 to 2 pounds of boost, is this normal for that speed or should I not have any boost at all till I go higher in speed. How much does the wastegate play a part? I have a Banks Big Head wastegate installed. Im still learning and trying to understand it all.

At that speed I usually see more like 5 lbs of boost. But i suppose it could be the difference in the mods I have versus the ones you have.

I usually saw 5-8 in my stock tune, but I have my red tube pulled and plugged going to the waste gate and I tightened my actuator rod. I would think that is low. You probably have a boost leak or your rod is too loose. Then again I dont know much about the banks, but when I asked a vendor about it he said you can just tighten your rod and get the same affect.
