it all depends on the wallet.. turbo is awesome but you wont gain a huge amount over the whipple unless you can upgrade your internals too.. i know i know turbo makes more hp per psi blah blah.. but it has to spool. no matter what you get there will be pros and cons. i would try setting up what you got better you might be surprised. If your gonna drop 2k on a 6.0 and 5k on a turbo id just spend the money and get a new 6.2 crate motor and be done with it just my 2 cents.. dont get me wrong though a turbo 6.0 would get you movin just lot of money too me by the time your done
