Default lsxr 102mm manifold
Hello,

I have a lsxr 102mm manifold laying around and I was wondering if I install it will I need a retune?

Current mods is a A&A v3si kit with a 4" pulley.

Leave it off. Causes more problems than it helps. Sell it and use the money for a meth kit or headers.

is there an aftermarket fuel rail kit I can use while keeping the ls7 injectors without having to use spacers?
