Default K04 issues, Please help!
i just had a ko4 installed with giac chip on my 98 A4, running stock exhaust and 4bar Fpr, however from 2-4k rpm the car is jerky, like its choking on something, 4 1/2k up its pulls strong and smooth, anythig below that is not much improvement from k03+ams stage 2 chip.
could you give me any suggestions, why the car is running the way it is, do i need new 380cc injectors?
Appreciate the help guys.

You need a 5 bar FPR.

Get yourself a 5bar FPR and a colder set of plugs.
