So I need your help!!! Please.
I was told by a tuner if I remove cold start it will damage my high flow cats!!?
Is this really true?!
Any help will be greatly appreciated!
The only purpose I found for cold start was for emissions and heating up the cats faster so they reach operating temps faster. Catless or even HFC doesn't need it.
You should ask the tuner why they think its terrible because I'm wondering too lol.
