Take some pics of the drivers side of the turbo(vacuum line routing ) and the passenger side of the turbo(looking for external WG) and post them up here. You will find out how you are controlling boost.

Oh... well I'm in the middle of fixing a manifold leak right now. But I can post some turbo pics of the turbo OFF the car if that helps. The bolt in the vaccum line off the intake side was there when I took it off.. is that where some forms of boost control should be?

The line that is plugged with the bolt normally goes to the boost control solenoid up on the valve cover. With that setup the only control is with the adjustment on the waste gate actuator. At least it is not hurting anything connected that way. It will keep the boost down at a low level. I would find out from the previous owner why it is plugged and not connected to the solenoid. Possible bad solenoid? If that line was left open you would have no boost control and your boost would go way too high and damage the motor. What chip is in the CPU?

Some no name tune shop chip

Looks like the chip is written for 93 octane gas, 50lb injectors, 20 degrees of timing, and 16-17 lbs. of boost. Any markings on top of the chip?

Just basically a repeat

Looks like an old Joe Lubrant chip. Your setup uses an adjustable gate and the stock boost solenoid.

Joe did a lot a chips sometime ago. He worked at Caspers Electronics for awhile. Now Eric (Turbo tweak) has the best chips.

Lets not be biases, but both Full Throttle and Turbo Tweak has the best chips

If you say so.

So what should I do about my boost control setup?

Use the adjustable rod and leave the solenoid hooked up.

To start unthread the rod until it's easy to hook on the puck shaft. Got an aftermarket boost gauge?
