I blew a very large crack into my Ultimate Racing steel "tubular" manifold, and I will be switching it out for a cast iron log manifold, is it possible for me to run the new manifold without an immediate retune? I plan to retune eventually, but this is my daily driver and the crack has been getting worse (came from hairline to paper clip sized)
so what do you guys think, would it be alright (in your opinion) for me to run this temporarily?
Thanks!
