I've got a USA spec 1985 2LT factory turbo engine. I've noticed that the timing per the FSM differs from the emission sticker underneath the hood that's a factory sticker.

If you compare the timing spec from the FSM to the spec under the hood, there's a .13mm difference between the two. Also, there's no spec for a 2LT with the ACSD removed which I have previously done.

I also have swapped in a TD04HL-15t and can hit 20psi quite easily. Given the information and the specs below, where would you go about setting timing for a 2LT w/o ACSD?
