LOL - the hassle you get with owning a ford rs eh...

right, my escort cosworth (T25) is overboosting,so when this happens the defender cuts the engine as a precaution...fair enough....so i got my hands on a chip (Cheers AJ),its a superchip,the car feels slightly quicker,but it still overboosts the odd time.the boost is sitting on roughly the end of the solid bar on the standard turbo gauge. any ideas? i cant get it set up for another month
