Hello.
I have a problem with my car and iam not sure if it is a mechanical issue.

Let me just say the history. I had a problem with the boost pressure sometimes i have boost 1.5 bar till redline but some other i had 1.2 bar till redline,after the help from steve i realise that i hit the requested limit baro specific ,so i make all the sells to 3.5 load and without any other change to my tune i flash the car ,now my car always keep 1.2 bar till redline and never 1.5.

I log the wgdc and i see that from, the 4000rpm and up is at 100%

Any suggestions??

I can post logs if i asked to....

Please list your mods. You may have hit the flow limit of the K04.

k1 rods,wiseco pistons, bnr stage 2 turbo ,forge wg ,grimspeed in interupt mode,cpe fmic ,cp-e cai,cp-e fuel pump ,full race header, 3 inch de-cut dp and 3 inch exhaust....
I think thats the basic.

The wired think is that before i raise the limit baro specific i sometimes have the 1.5bar till redline, thats my issue.........

WGDC of 100% means that you reached the maximum flow capabilities of that turbo in the ambient temperature at that atmospheric pressure. Stop looking at the boost and start looking at the MAF g/s and see where you are compared to when you had 1.5bar of boost.

Post a log and your tune, maybe someone can help.

I found the problem ,the turbo is off......
