Dumb question… I’m sure this has been answered somewhere, but I couldn’t find it through the forums. 2022 m340i xdrive. I currently have 14k miles.

Whats the most power I can get without sacrificing to much reliability. It’s my daily till I get a 2nd car. I recently purchased Dinan intake, Dinan turbo inlet and Valvetronic full exhaust. I’m waiting on purchasing my AA down pipe that everyone recommended for when I have a bit more spending power which will be after the holidays. And obviously a tune for it once my warranty expires this upcoming spring. I guess my real question is once I’ve unlocked the ECU, what kind of tune have you guys done to get more power but still keep it reliable. Is there anything else I need to do or items I need to purchase to upgrade for more power so I’m not blowing my motor hurting the car? I’d don’t mind spending the money as long as it benefits the cars longevity.

I would search the forum due to several threads on this topic and some useful answers that have been shared from many that have different power end goals and various experience. Plenty of great info already on this forum.

Even stock these cars can have reliability issues. It really depends on how you drive it and maintain it. Modifying your car to have more power than the factory is always a risk. Having said that I believe a JB4 piggy back tune is low enough risk. The flash tunes are probably even safer but 3 times the cost. I was full bolt on with my '15 435i. I ran BM3 stage 2 for at least 3 years maybe more with no issues resulting from the tune. Traded the car in at around 75k miles running fine.

A simple piggy back with less than 4psi additive should be ok.

As long as you are using normal fuel like 93/98 and a good tune like MHD or BM3 you'll be fine.

But if you are getting a tune don't waste your money on an AA dp, get a MAD or VRSF, much cheaper, flows better, same quality. Will just throw a Cel that the tune removes anyway.

The AA DP is rated for north of 850whp, and you get the benefit of zero smell. Any flow difference would be negligible on a dyno. But I agree that a 200 cell DP is significantly cheaper.

It's slightly better than oem but nowhere near a catless. Rated flow and real world restriction are two different things. There are dynos and data logs showing fairly large restrictions with the gesi cats in the 500whp range. If a code compliant cat is what your after it is what it is. Catalytics and hp gains are just not the best of friends.

I agree for flow. But your reference is referring to a pure 800 turbo setup pushing 500whp and is comparing a catted AA to catless, not 200 cell. The gains between 200 and 400 cell on a stock turbo isn't going to be much different. Though I did clearly overstate the capability of the AA at 850whp after reading that thread. Lots of good info in there and if I go that route I'll be changing out my AA

Keep in mind that if you have emissions testing requirements in your location, then you’ll be better off with a catted DP.

I passed emissions with my setup:
AA DP
Mission Tuning 93 tune
Eventuri intake
