    Change the intake, add MPFI injector harness to TBI harness, change fuel pump intank to TPI and hack the PCM.

    If your lucky the truck would have 16197427 $0D or $0E or varient and the hacks and all info is here.

    If you have the 4L60E or 4L80E then the PCM that currently in the truck can be converted to TPI. Many details are involved, but the TBI to TPI conversion has been done several times.
