Right this is getting beyond me, ive put spanking new injectors and fuel pump in, have no exhaust ir turbo leaks, no vacc pipes have come off so i can see, ill double check underneath the car tomorrow, its lean when idling and runs lumpy all the time its off boost, but when boosting up to 8 psi it fuels bang on but anything over it goes off the scale, pleeeease what am i doing wrong????!
