I agree on the price for 100k more it is a lot of that extra HP but if the option are more on the 528 then it will be worth it.

Yeah, if its the same physical stuff, adding a tune to a 520i would just be making it more of a 528, while adding more ontop of the 528 to like 300hp u create more stress, so more likely to break..
