Mine was hesitating like hell after I had a boost controller fitted. I took it to WRC Tech last week, it was running dangerously lean between 3k & 5.5k, luckily Chris spotted that the pipe had been knocked off my fuel regulator.mike_turbo said:thanks for the link and advice too guys - basically the car has felt like it has been hesitating like f*ck for a while now, i put this down to plugs but they are less than a year old but i ruled them out, but we are gonna try and rule out the easy ideas first - see if that helps
