right i have got a power boost valve fitted on my car and it has been on for a while but i am not sure if it is set up correctly. how do you guys set it up or is it best done on the r.r.? oh and what wheels do you lot have as i am having real difficulty finding et49 in 17"! forgot to ask some one said about removing the orange bit from o.e throttle bodies on a c20xe so where is it and how do you take it off? and what does it do?
