After putting alot of thought into it, I just gotta stick with the stock efi and vvt. It doesn't make sense not too. I used a Mopar Crate Harness in my last swap and it was really nice to work with.. But I didn't have a harness at all, so it worked out best. Depending on whether I get a setup that includes the harness or not, I'll go with either the MCH again or Sublime (DIYHEMI)
