Why?

 

Well, that is part of the original question (whether it's advisable or not).

If it is advisable, might it reduce engine wear? Reduce points of failure? Unlock more power?

If it is NOT advisable, might it be because it can damage the engine? Result in higher fuel consumption?

I'm trying to learn so I'm asking. There's conflicting information online and I thought I'd ask people with actual experience.

EDIT: I've also gone through threads on this forum, but most are related to EGR valve problems rather than whether a delete is a good or bad idea.

EDIT 2: I live in a country where there are no emissions inspections (or any other kind of inspection, really, other than VIN checks).

EDIT 3: I'm also asking because my local mechanic says he does it with every car he works on, but he mostly works with pick-ups and Japanese cars (from around the same era as the e46, though). So I don't know whether to follow his advice, or whether there's something specific to the e46 and this engine that would make it inadvisable.

 

wont hurt anything, would also deep clean the intake tho

 

Thank you for the reply!

Is that true even without a remap? I don't have access to remapping in my country.
