I have no personal experiance owning anything with TPI so I'm the wrong guy to ask about that. I have had several with TBI and have absolutely never had a bad issue at all with it. When I replied earlier I forgot you had that extra TBI motor, sorry about that. You could always throw it on the Suburban and rebuild the extra block, then while you are doing that you can research what injection system you wanna go with. Then you won't feel rushed into making a quick decision. That's probably a route I would consider taking.
