Maybe. Truthfully though, im just not interested in that. I want to take it back to being a little more simple. I dont want so much mix and matching. I want to mostly, completely rewire the whole engine instal to make it a lot more factory as opposed to how i just tied it all in like i did the first go around. It would probably work forever if i went back with the LS1 tune and kept the wiring just how it is and had a tuner custom tune the fuel/spark maps. But thats just not quite what i want. I want it to be a 1990 suburban with a factory 5.3. If that makes any sense.
