I'm sure it's been beat to death, can someone tell me where to find "2015 235 n55 first performance mods"?

Hopefully including some brands as well, I'm new to bmw and don't know the good and bad brands

It's a daily, will never be tracked. I just want to make it super quick, and sound good, not too loud. I don't know exactly what I'm aiming for as this will be my first build. Just mo powa baby. I'd also take advice on looking out for the stress spots.

If power is all you're going for then the build list is relatively simple, however, it's still important to be able to handle that power and put it down properly.

I assume you're interested in digs or rolls, in which case I would consider optimizing your grip by going as wide as possible in the rear which seems to be 265, not much, which is why its so important to try to get as much in there as possible. Follow this guide:
https://apexwheels.com/fitment-guide...-fitment-guide . Choosing the right tires is going to be very important when it comes to getting the right amount of grip in but it depends on your environment.

obtaining power is pretty simple and you have two big options for tuning, Bootmod3 which is what I ended up choosing, or MHD. Both are valid options with many backing up them both. No real upside in choosing one over the other from what I've gathered.

Reducing back pressure is #1 in turbo cars and it's mainly caused by the catalytic converter. Ideally you'd get a catless downpipe but if emissions is your concern then I would either completely forgo this route or buy an epa compliant high flow downpipe which can be pretty expensive. For a catless downpipe I recommend VRSF, great pricing and they get the job done. Other great brands include Evolution Raceworks and CTS. To any other forum members, if I'm missing any feel free to add more onto the list.

An intercooler is a requirement for stage 2 tune. I honestly dont knwo of any issues popping up from a "bad brand" intercooler. All of the seem to be great options.

A common stress spot for the n55 is the charge pipe which will crack under additional boost added by the tune. Replacing the OEM chargepipe with one made of aluminum is what everyone does in order to prevent any issues from popping up.

There's always more to to do to add more power but this is a relatively simple and cheap way to add a lot of power to your car.

X-ph has a combo deal that looks very enticing

Thanks for all the information man.
I found a post where a guy did this and it sounded like he had some experience. I was thinking of just copying him, what do you think?

JB4 tune with Bluetooth controller
Burger Motorsport intake
Burger Motorsport chargepipe
Burger Motorsport intercooler
VRSF catless Downpipe

The car is an x drive, and the precious owner stanced it pretty good. The rim sticks out from the top of the fender a tad.

Emissions isn't an issue here.

Digs and rolls is really all I'm looking for. Just Wana show off a bit.

Kboustani was the user with the setup

That's a really slick deal, just need the exhaust if I'm not mistaken. I think I might get that when I'm off work.

I'd suggest MHD or BootMod3 instead. JB4 is fine, but I'd personally go flash tune over piggyback. Piggyback can never be as smooth as a real tune. Also consider some fresh subframes bushings, transmission mounts, engine mounts, etc. Once you go above stock power, that old rubber starts to give.

I'd suggest to go with VRSF parts since they are very reliable and cost efficient;
1-Chargepipe (Must) $219.99
2- Catless/Catted Downpipe depending on ur taste and the law in ur state. $269.99, $479.99
3-Intercooler (If you are tuning to Stage 2) $479.99 + Boost pipe
4- MHD tune $543.18
