Hello,
Just a quick one, I'm getting random big boost surges, sometimes feels like youve caught the break by accident as you pull away if you get what I mean?when it does this you can hear it give a massive dump too, Some times the car pulls very well and other times its slow then half way through the revs it'll suddenly gain power like someone is flicking a switch if you get what I mean? I have replaced maf sensor and checked all hoses and I'm starting to think n75 valve. Is there a way I can test it or disconnect it to see if it makes a difference? No fault codes by the way. Cheers
