    1. Fuel pressure 43 or 58 psi, depending on which map you are on. (refer to back of manual for MAP matrix data).

    2. First gen sumps were not adjustable, came preset. If your's has a vac port, your's is adjustable, again check E tuner home page (on tablet ) for the MAP #.

    3. CDI box is not necessary, will run just fine without.
