Diesel pump advancing ?

[marckb]

Hello Isuzu fans ,

I'm new here , and would like to ask questions how to advance the diesel pump . I live in Suriname and here we do not have dyno to tune car . I have a Isuzu TFS 2001 P/U with 4JB1T engine and have done a intercooler upgrade , adjust the fuel and run the boost to 14 psi , also have put in a 3 " freeflow exhaust and a
oil catch can , waiting for next week to get my pyro meter .

Hope to hear from you how I can adjust timing for the pump .

Thanks MarcKB.

Ok , ok ,

I did it alreidy , I have ordered a special adaptor to connect to a timing light , conectect to cyl 1 and advanced the pump about 4 degrees , pulls lot better now thru the whole rev range .
