Boost issues with V2 STI. HELP!!!
Hey guys, so i recently bought a V2 sti wagon and it came running 6-7psi which i know myself is quite low, took it a specialist briefly who found no error codes but switched my boost hoses over as they were incorrect which now runs 10psi. however turbo spools up great to 10pis but on hitting 10psi when foot is flat it shudders and bunny hops in a way that is like a boost cut. have had spark plugs and coils checked as well without any problems in them. please help!!!!

Most likely as above, Buggered spark plugs or the coils are on the way out.
If you have to replace them, I would upgrade to the later model versions! My car was a complete different car after changing to the new style! I had this exact problem!

I had the coils and spark plugs checked out when the problem developed and they were fine, car runs great and spools up to 10psi its when i put foot down it tried to go higher and then sort of boost cuts and the car shudders and almost like a stall. the car doesn't have nay error codes and never turns off when this problem occurs it runs fine if i take foot off again. thanks

I would still suspect the coils, The smallest of hairline crack or anything can cause this problem!
When I had the same problem I was sure the coils were fine.... When i upgraded them the problem disappeared.
My 2 cents

This is what solved my problem!
I also had no problem at 0.5 bar! When it finally ran full boost it was bucking like a horse!
