the car has been tuned by castle engineering,who fitted the chip and injectors.its running a rst pump i think.i didnt own the car when all the work was carried out.is there anyway of telling what fuel pump im using?

i looked again at the amal valve and the (c)and(w)where conected as follows....compessor(c) was connected to the actuator and the wastegate(w) was connected to the compressor!the other one is not connected to anything.could this have caused damage?when i reconnected them properly i took it for a short drive and it boosted to over 1 bar(14psi) and didnt cut out.it wanted to boost more but i felt it would have gone BANG.i did however run out of fuel i think?!the fuel pump sounds like it is sucking air out of the tank.a sure sign i rekon of no fuel.lol.my gauge however shows that i have just under a 1/4 of a tank.

the backfiring and cutting out was still happening when i put 20 bucks worth of petrol in her.
