So when I get home this weekend from a work trip my upgraded turbos from 4DR will be waiting for me. All-in-all plans are for turbos, downpipes, meth, and a dynotune at Livernois. Due to work scheduling I probably won't be able to get up to Michigan until first of the year.
I know I can toss on the upgraded turbos with no tuning issues but I might as well go ahead and change out the downpipes since they have to come off anyway. I'll be itching to go ahead and install these so I will get the PPE catted downpipes and put them on to.
Will adding the downpipes also cause any issues by running my current LMS 93 tune?
