Boost Problems

[Cuprani]

Im running a ko3s with a stage 2 remap.

Ive started to get boost problems, if i put my foot down she will wind upto 10-12 psi before shuddering, its as if the turbo is coughing.

It only does this after 10 psi, what could this be? ive been to 4 different garages now and they dont have a clue, ive looked through the forum and can find nothing! does anyone have/had this problem.

Help will be much appreciated as im at breaking point.

Cheers

Sounds like it could be a coilpack on it's way out. Mine was doing this recently and changed the dodgy coilpack and it was fine after

You need vag-com to work out what one it is as it won't be fully gone yet.

agreed sounds like coil pack mate take em out an check the connection underneath should be a copper color if it is dark then that is the one
