I have replaced my nozzle tip for my Mits. Strada 2003 L200 4D56 Turbo Intercooled engine, since I have been experiencing black smoke when climing uphill. I have seen the brand of the Nozzle which is ZEXEL DN10PDN130 which was the OEM for it. and some says I can use a DN0PDN120 which is NIPPON DENSO. Is their any difference on both Nozzle's? Is there a OEM Factory data that I should know? and some other calibration shops here can't show me a factory data specifications what pressure to use on this nozzles? Some say pressure is 140PSI some 130PSI or 150PSI?

Can you help?
