This is what I've found that's available now. All claim performance boost (HP/TRQ) except Dinan.

Anyone have any of these? I know some have the Dinan.. ASEChips/AA/HS claims the biggest gains..

Wow, lot's of chip threads as of late. I think we only have word from people who have installed dinan. 1k + for software is ridiculous, this isn't an s4 or turbo.

I'd figure no one put all the ones available in one thread.. so i did it to keep the info together..

Which do you guys think is the best bang for the buck?

Autothority looks good but no mention on price. Bav Auto is ridiculously expensive..

How much does the dinan software run ? :dunno:

www.dinanbmw.com .. gotta traverse to the pricing page PDF.
It costs $399 + install (which is like 50 bucks)

I'm highly skeptical about some of those gains they're posting.

Lack of independant and confirmed testing of these chips is not helping. :confused:

You may also add Kelleners to the list.

Their website DOES mention a price:

How does $2,500 sound? We should all line up and buy it eh? =)
