Ok, so I got an APR chip for my 1999 B5 Audi A4 1.8t a few weeks ago... Great improvement to performance btw...

Now I'm thinking about getting a Borla cat back exhaust system. My friend says that will mess with the chip and that I'd have to get it reflashed after I get the exhaust system. I'm inclined to disagree with him because logically that would mean I'd have to get it reflashed after every single engine upgrade/change, but I'm not 100% sure so I thought I'd ask if that was true or not.

 

WTF? i dont think so correct me if im wrong guys. because i have on borla exhaust and about to put on APR chip in a few days.

 

Alright, so I should be fine then... I'm not going to get bigger injectors for a while, first I'm going to get the Borla exhaust and then probably find a cold air intake. Thanks!

 

I got the chip from an APR dealer; they will still reflash it for free right?
