hey everyone, my wife's 2014 Passat's turbo kicked the bucket at 86k. I've purchased the Darkside 200HP kit and had a few questions.

Should I still purchase the upgraded oil feed line and drain line from VW or are the supplied variants adequate?

I really am looking for longevity, reliability, and highway fuel efficiency, hence the swap to a larger more reliable turbo. Since it's my wife's car and she doesn't need to hotrod it, what should I do for a tune? The one tuner I spoke to said he can do a Malone Stage 1 even though this is a CR170, I just need some validation that he's right and that that would be the best option.
