I'm not ready to buy a K04 but I just want to know how many internals I'd have to switch out or if I can keep it relatively stock.

 

Try searching on "ko4" there is tons of info on the different k04 setups. Here, I'll jump start you: https://www.audiforums.com/searchpro...bmitbutton=+OK+

Also it helps if you put the specifics of your car in your signature-like what year/engine it is.

 

No internal changes needed for a K04. Just programming and fuel pressure regulator and the turbo

That itfuel, turbo, and program wow how much psi can u run with that setup? David9999

 

wrench, the tuning comes in the program you get along w/ the ko4 upgrade. the fuel/timing/boost levels are all taken care of by the chip. the ko4 will do 19 psi, i wouldnt reccommend much beyond that. go w/ the pc-16 file by giac, good stuff. :thumbsup:

 

Your gunna need exhuast, injectors, afpr, and a fmic to use the pc16. All you need is the 5bar fpr with the basic k04 chip.

 

most people who go bt dont even change internals..

 

thx for the help
