Tune for high flow cat delete?

[joe5oh19]

I’ve been looking into deleting my high flow cats that came with my tsp headers, would I need a tune for this? My car is already tuned on e85. Thank you

No. Lund told me it wasn’t necessary when I deleted mine
and it’s been running great.

Will run exactly the same, just sound crappier without the cats.
