Cat delete vs e85

[Romclean]

I’m debating between doing a cat delete with revised 93 Lund tune or the Lund flex tune e85 option with 47lbs injectors. Which one would net me more horsepower and better track times? I currently have a 2016 gt auto with the 2018 intake manifold mod and 93 Lund tune.

e85 , only do cat delete if you go forced induction and e85 imo.

So the e85 tune would outperform the cat delete option?

Definitely, your motor will also stay cooler and your exhaust wont smell horrible like it would if catless on 93. It will actually smell good if you run e85 and keep the cats. And the sound wont be insanely loud like cat deletes.

Absolutely, especially on an NA application. If you have E85 to fill up with readily, I would definitely go for it.

By FAR, not even close tuning for e85 will outperform just a delete. Plus the cooling properties are an added plus. Save the delete until you boost later.
