How new is your o2? And turbo pressure signal usually pops up when you hit fuel cut. And the pressure signal unit could be going bad

Yes because our ad in mk'3s seem to short our knock sensor wire or wires. So to make like easy you just solder the knock sensor on new wire and run it back to the ecu.

Works Everytime ;)

for real i dont gotta ground shit? like i really wanna do this just i do not know what kinda wire to use?!?!? and whens fuel cut :S cuz i retimed the car last night and before i could squak the tires it first now i just spin all the way threw first half way threw 2nd and going into 3rd.... idk if i did something wrong or what... plus my boost gauge is reading 10psi steady and all i got is full 3" all the way back and 2.5" metal ic pipes and bigger front mount with a non resirculating bov and kn cold air.... so idk.... and after boosting idle satays at like 1100 for like 10 mins....

well 3'' exhaust and the nicer IC piping free up the turbo thus more boost thus more power. Seems like your timing was off before because now you are making more.

And i think if you just use 14 gauge or 12 for the knock sensors and wrap it up in some heat shield that you'll be fine

There's your problem, recirculate your BOV. Your AFM is reading all that air coming into the engine that the engine will never see because it's being just blown right back out your BOV.
Rewire your knock sensors and get a new turbo pressure sensor and it seems all should be good.

No.

Go to radioshack and buy a 20ft microphone cable and cut the ends off and use that as it is nice flexible shielded wire, otherwise you get interference and you will have issues again.

ok... so i need a resirculated bov? is there anyway to make it so i dont need to resirculate it? and its got a jdm ecu if that makes any difference... usdm engine jdm ecu....
Electronicly with either an HKS EIDS, or an Apex-i S-AFC.
They both are for modifing the AFM signal during decelleration, so that the ECU doesn't try to deliver fuel for all the air dumping out the BOV.
The HKS EIDS only does this job.
The S-AFC does so much more.
