    I am sorry for the confusion.

    I have a 99 OBS Chevy OBS 4x4
    I also have a 411 PCM that needs to be installed. Install is easy (just time consuming) need to take each wire and just re-pin it.

    What is going in...
    6.0, 2wd 4L80e, E-Fans from 06 Sierra

    At this point it is just a bunch og big what IFS...my plan is to run pipes back to Dynomax crossover X muffler (built in X Pipe) then exit out the side before the rear tire.

    I really want boost, just waiting for the right opportunity to do so.
