boost leak?
 

I just put on a s300 turbo p/n 174430 I know its not a big turbo but I got it cheap. It works good but im only seein 30-32 psi max. I thought id see 40 at least. Any ideas?

This will tell you if you have a boost leak:https://www.dieselbombers.com/dodge-...tructions.html

You may just need to adjust the wastegate.:pca1:

Where are you hooking in your turbo gauge?

Into the intake manifold

swap out the glowshift for a different gauge I would not be surprised if it's off. Plus your smarty is not going to give boost numbers like a edge comp or similar product will.

Yea I agree. I've been unhappy with these glowshift gauges.
