Hi all. I'm looking to add a low level of turbo boost (10psi or less) to my factory V8 Colorado, 2009 5.3L E67. Can this be done via HPT using the factory operating system? I think I need to keep my original OS for the dash to work, etc....? Not exactly sure if positive pressure fueling can be added to an operating system which did not originally have it, or if HPT has the capability to do it. If so, is it just a matter of adding a boost type MAP sensor and extend then adjust the fueling tables?
Thanks. Want to get this determined before I buy hard parts.
