    I'm still alive, I ordered the PCM this morning, after this I believe it's game on.
    The reason the marine engine has more H.P. are the injector size. Stock S10 spider injection (poppet style) are a 19 lbs. injector.
    The marine injectors are 26lbs @ 58# of fuel pressure and they'll get you 290 H.P. with a turbo set @ about 5.5 psi
    This same fuel pressure on the stock poppet style will be about 23 lbs.

    To be continued!!!
