I had my injection nozzles replaced and calibrated but since the mechanic said that the fuel pump doesn't seem to have any leak or something so he advised against tampering/calibration of fuel pump. Is this okay? Yes this is fine. Your mechanic was trying to help you. Are you happy with your car's present performance?

Thanks! You're welcome!!!!!
Dieseldude, yes I am happy with my van's performance after replacement of injector nozzles. Less black smoke and more responsive. Thanks.
