    adjusting timing on boosted lt1

    I just finished my turbo lt1 build trying to get the timing set right. If any one has a .cal file to compare would be real helpfull but any advice would be great right now im running max advance of 28 degrees in boost.

    what year PCM are you playing with? i assume 96-97?

    i've patched a DA2 or DA3 BIN for boost support before, it could be done for EE as well, but i haven't needed to play with the 96/97 setup before.

    i've always wondered, how the hell do you adjust timing for something that creates manifold pressure above the limit of the ECM's timing table?

    do you just do all your timing @ atmospheric and have it flat in boost?

    just curious.
