    I may end up going this route or something close to it. I even considered using the MPI spider with a few modifications to fit in the nitrous bosses of my air gap intake. Would have to look closer at it to see if it would be feasible, or if I could even get the injectors to spray in the rite direction but it would be an interesting setup.

    Did you ever find anything?

    I am considering selling my Edelbrock 3505 Vortec MPFI intake and Holley 670 throttle body and running something that self learns.

    I imagine the emission output per horse power ratio is very high on that horse.

    Why not OBD2/0411 swap that intake setup?
