I've seen a lot of mixed reviews about this, I have a 328i xdrive n20, and debating on adding a few extra hp(50-60) if it will still be reliable as a DD. Was thinking of doing tune stage 2, intercooler, charge pipe, catted downpipe. Do I need anything else? Or is some of this unnecessary to achieve my goal? Also biggest question is it safe to do all this on 91oct? The way gas prices are right now i couldn't really justify paying 30-40% more on 93-94.

30-40HP is safe on 91OCT

When I stayed out of boost I would average 22-25 mpg in the city and 30-32mpg highway. You'll get better gas mileage making the car breathe easier and keeping lead out of your right foot.

Intercooler + pipes (boost + charge + turbo inlet + downpipe) and up to date maintenance.

it's safe to use 91 as long as you are choosing stage 2 91 maps from bootmod3

We offer combo deals that take you from stock to stage 2 at a discounted price.

I thing its fun to get that extra power from the n20, I have all the mods you have listed, I had problems with the CA 91 so I just recently changed to a ethanol blend and it runs ten times better, bm3 makes a great daily tune in my opinion

See thats the only thing holding me back right now, I want to keep her on 91 oct without any issues, but also crave the extra power.

Interesting.. but that make sense. I think I would have a hard time keeping her out of boost. would these mods without an actual tune show some significant improvement? I could also just add sport+ mode to my car and use it whenever i want to have some fun.

That's the annoying part with California gas, you will still feel a difference but from my experience it was very jerky with the throttle and each gear felt sluggish
