tried going directly to UIM and to vac block with same results.

And you added an L36 LIM?

What did you do about the injector bosses?
Yes was L67 and replaced the M90 case with a ported L26 LIM. Injector bosses tig welded closed and vac gauge is reading -18 at idle.

Either run an L36 bin file with a 1 bar MAP sensor or run an L67 bin file with a 2 bar map sensor.
You can use a 2bar MAP sensor from a 2004+ GTP on the L36 UIM.
Running L67 MAP





I also have an enhanced AFC that I might start playing with.
