I drove another forum member's car last night and his boost seemed to come on a lot sharper than mine (both of us have stock CT26s and Profec B boost controllers with identical settings). I'm thinking the spring on my wastegate is hosed since I only pull slightly less than 6 psi with the boost controller off. Can I replace/upgrade the spring?
Note: I had the turbo off the car 13,000 miles ago and didn't see any cracks around the wastegate port.
