    1998 MPFI Conversion & 0411 Source?

    Is the SKP SKFJ504 on RockAuto (~$350) a good option or is there a better choice? And then another question, whats the best source for an 0411 PCM? Should I search FB Marketplace or should I purchase one from an online retailer? I was told Black Bear is hit or miss for tuning them too.
