As for boost, no idea. How do I check that? I do have the USB cable... can I go in and increase it? If so, what is the highest level that will not blow up my turbos or slowly kill them?
should be 3-3.5 PSI if you havent touched it. As far as hurting the turbo, its maxed out from the factory at higher RPMs, cranking it up will only make the boost spike at low RPM hit harder, maxing the turbo out wont hurt, but exceeding the amount of boost for a given octane will cause detonation, or the vehicle pulling timing to try and save itself.
