Anyone know how I can run a larger DBW (LS2)throttle body on a gen 3 engine??? Haven’t purchase a harness or pcm yet what are my options? I’ve heard the x link is an option. Anyone have experience with these. Is that my only choice?

I have a silver blade ls2 tb on my 02 Denali early dbw harness with just an adapter cable. It's basically parts to put an ls2 tb on a dbw ls1 c5 Vette. You can't use a gold blade or 03+ dbw with this setup but there's probably another way to do it using a different combo of parts.

If you are going to go with the ls2 tb make sure you have an intake that has a hole at least 92mm.
