I am toying with the idea of putting an sts turbo system on the truck since its lifted and has larger tires in order to help get up and go. My first question is would the factory injectors be up to the challenge. I am aware that the factory injectors are able to handle some boost but would this be advisable? Max 5psi. Also from sts they have the additional option of buying the injectors and diablo tuner for 1500 which to me is way over priced. Any thought? Thanks
