Hi guys, I am rebuilding a 1988 mechanical 8V92TA with TV8513 (1.39 A/R) turbo and 9G95 injectors.   I can not find any tune up specs for this configuration in any of my manuals, or the 2 Field Service data books I have (1991, 1996).  Do any of the 8V92 guru's have the injector timing for the 9G95's, I believe this is a pretty common upgrade for the 8V92 so hoping someone has this, or knows where I can get it.  Thanks.

Same as the DDEC 1.500 or 1.520 you go with a 1.480 then you have a smoker.I use the 1.520 with high calibrated injectors and 1.500 for the low or medium calibrated injectors,if you have the truck engine section the setting are there too
