Is it tuned?

Brownbrothers · (#6)

as far as i know it is not tuned and i now that its not ideal to run a ko4 on oem softwear but i didnt think it would run improper but im not sure

eurotrsh · (#7)

I think that may be the cause for some of your issue. Im no motor/turbo geek but your ECU isnt designed to work with that turbo.

yeah i have herd that ass well im working on seein if i can get the ko4 file that doesnt need me to upgrade my injectors just the fpr to a 5 bar
but im working on trying to find both

I think a 4 bar fpr, injectors, and ecu flash are needed. Check the 1.8t FAQs on vortex. There is a list of things needed for a K04 to work properly.

^ word, 5 bar is more than u need. that k04 isnt going to flow that much.
