Yep, I am going with the ls1 computer. About to send it out to have it modified. I have been looking at diagrams of the 87 fuel system. It looks like the fuel tank selector switch in the cab is indeed run through the factory tbi computer. It should be an easy fix though to bypass that part and remove the tbi computer.
