Help`

[wortho32]

hay guys just got my car bk from getting tuned.

it went good 4 a bit but now it is idling weird ( it goes up and down not rapidly but notice able)

the car shutters when i drive along the motorway the waste gate just keeps going of as if i was getting on and off the throtle.

i have changed my plugs fuel and fuel filter and still got the same problem..

any ideas?

you mean the BOV, not the wastegate.

I suggest you take it back to where you got it

It sounds like you may have a cracked/split hose running to your blow off valve. My friend came to me with the same issue on his r33, his hose was split.
