the other day i drove my car from perkaise,PA to cincy,OH(9-10hr drive) in my gs-t i get down here, and when i get on it my car the boost goes to 17psi then drops back down to 10psi, my friend said it was a boost line cracked or leaking somewhere but i dont know, so if you know anything plz tell me.

Build a pressure tester. Its a easy way.

Or do you have any ether? Spray it lightly around the intake. If the engine revs rise you found your leak. Arrggg...... It'll be smooth sailing from there.

How is your idle? Smooth? Whats the vac reading?
