Read this thread on the 10K pot. I learned a ton. Let me repeat what these fine folk taught me:

1. You need gauges (boost, pyrometer, at minimum).
2. Before adding boost...you need to increase air flow. That means.
A. A better air intake.
B. A free flowing exhaust. Start with a down pipe if you are low budget.
3. Now you can think about boost.

I just read you have the mechanical wastegate controller from Heath. You're out of luck. The 10K pot only works if you have the OEM wastegate controller.

How much boost do you currently have and what are you attempting to get?

Since you already have the mech. wastegate controller, you may want see if you have an exhaust leak. I found that three of the nuts that hold the turbo on the exhaust manifold were missing. I will find out tomm. if it has affected my boost at all.
