View Full Version : K04 setup with a Wett chip question...

A guy I work with has a '98 A4 with a K04 and a wetterhauer (sp) chip. He said he was told that he didn't need a 5 bar FPR so he didn't replace it. Does that sound right? I'm not too familiar with wett chips so I figured I would ask someone on the 'zine. Thanks

if the file is written for the stock injectors, it is almost certain the fuel pressure must be raised in order to compensate. Wetterauer would be the people you'd want to contact.

I would have to say it would be tuned at 5bar since the 98 only came with 240cc injectors and they are pretty much running at max on just a chip.

[rs4] If you don't upgrade your injectors I would think you'd be running a little lean with the Wett K04 prog. I upgraded to 310cc injectors and I'm running a little below 3 bar because at 5 bar and at 4 bar I was running far too rich. With 240cc and 4 bar I would assume lean conditions.
