Hello everyone,

I am trying to figure out what is possible with the B48 engine. I came across this video which is super impressive!

I am looking for an easy upgrade that I can make in my underground condo parking spot. Maybe changing the turbo, airfilter and coding. They talk about using ethanol which doesn't sound practical to me. I would rather prefer to not push the car too far and always get 91-94 octane.

My goal is to get to the numbers below but I wanna do this safe. I am also thinking that I will add the sport+ mode and program it to only push the car over stock when it is in sport+. It will be back to stock power on comfort/sport etc. which should be enough during my daily drive in traffic.

Current -> Goal
255hp -> 350hp (474 max in the video)
295 lb⋅ft -> 370 lb⋅ft (582 max in the video)

What would be your recommended tune to achieve this?

Thanks!
