C7 tune

I just did cat delete pipes, then i got a tune, but im getting midlength headers also . Do i need to retune again , ? Will it go lean even after the dyno tune?

Possibly, the shorty or mid length probably won't show much hp so and since they are so similar to the stock manifold you might be ok since you had an initial tune for your cat delete. Now if you'd changed to full length headers thats a different story.

Thank you for the input, i appreciate it! I kind of figured that, the reall restriction was the cats , these headers are the manzo modlength, not much different rhen shortys but without cats.

Hell you don't pick up much more then that with the long tubes. Sounds like the way to go and GM did a very good job with the Exhaust manifolds and that should prove that point.
