hi people, at the moment my supe will only boost to 0.7 been in and out the garage still the same now losing faith with them, someone told me to try sva imports at dover, went to see them and was impressed as they seem to know what there stuff,and have a rolling road i asked for a price to boost to 1.2 which will mean decatt ,boost controler ,fcd so to boost to 1.2 will cost me £850 ish does that sound about right. also my shocks at the front are shagged only had the car 6 months garage said its wear and tear, but will only charge me half price, so does anyone know roughly the cost of front shocks fitted,
