Hi, Can anyone help? I have increased the boost on my volvo from 7.5psi to about 12.5psi using a bleed valve on the wastegate pipe. On full throtle acceleration in 1st and 2nd I sometimes get a kick it's like taking your foot out and then back on the throtle. I understand that there is a boost control switch/valve that shuts down the fuel pump if the boost is too high. The curcuit diagram shows it but the question is WHERE is it? Some have said that it is near the pedals teed off the boost guage pipe, mine isn't. Does anyone know where it could be? This mod makes the 940 a prety quick car!! Clive.
