I just unscrewed the pyro probe and used run copper lines to a pressure guage.

 

ok I will try that tomorrow what kind of drive pressure should I see at say 20 psi boost?

 

Is this with your TST cranked and smarty loaded?

 

The smarty is always loaded and the tst comp has been on different levels. I tried level 7 today and still 35 lbs. I used to see 45 with just the smarty and the needle would shake violently around 47 with the tst on.

 

Short of Having a boost leak. Get that your head latched on and give it some more fuel.

 

What was your drive pressure before the cam?

Dunno =\ I checked drive pressure for the first time this weekend =/

Is it a 4.5 inch pvc plug I need to test for leaks? Or a cap?
