N54 owners in Melb with Cobb or JB4
Hey guys im looking to finally get a tune for my n54 and have pretty much narrowed it down to Cobb AP or JB4. I've read alot about both these tunes and I guess there is only so much you can read. I was wondering if anyone in the melbourne area with one of these tunes be nice enough to meet up with me so I can see first hand how much of a difference it makes over stock.
I'm located in the south-east side but work in the city
