would the Charge Control Valve not working right cause the second turbo to only make 0.6 on boost gauge.? Thanks
If you haven\'t already seen this website, it maybe worth reading it through. It may give you some ideas.

(But obviously if either your air bypass valve or the charge relief valve and even the charge control valve, don\'t work properly, then there will be boost issues).
