No matter what tune its only showing 20psi max on the CTS. Does the cts show max boost or only what the map sees and if its programmed to only go so high will that affect it? If there was a 6.0 van turbo would it not make boost like a truck turbo? We checked for boost leaks and the IC was blown. Replaced it, no more leaks, and still only makes 20ps.
