I would like to upgrade the turbo on my a6 2.7T. I know the next step from a KO3 is a KO4. Although, i am unsure on what the KO4 performance increase would be. Anyone who has made the switch please comment or someone that knows a good bit about the power increase that will result in the change.

I also would like to chip the car at some point. I was thinking APR as i have heard from multiple sources that they are the best. If anyone disagrees with that statement please tell me why as i am flexible right now and i am not set on getting an APR chip. Also, would it matter if i chipped it first then gotten a bigger turbo or would it be better to do the turbo upgrade then do the chip?

Thanks in advance

Get a chip first and if you still want power, then get a turbo upgrade. If you want to know how much power, look at the S4 forums. THey have done the upgrade lots of time and will have basically the same numbers as your A6

thanks for the help cincy, that is what my brother said to do but i was just trying to see if anyone online agreed or disagreed.
