Optimize a B46

xjayceeg20 · 10-02-2024, 01:51 PM

Just got a 2019 BMW 330i base model with a b46 engine , looking to get the most HP out of this engine I have watched vehicular DIY’s videos on youtube but do not have the confidence to do what he has done to the engine myself I’m worried about messing something up in the engine bay and not being able to fix it , this is my daily but I want the car to have more power, so far the only thing I have done is a muffler delete, and the rear muffler/resonator delete. I have the dinan cold air intake coming and I would like to tune it just not sure what tune to get. Let me know your opinion on what else I can/should do to it!

Both the exhaust mods you did or the intake will not get you more power.

You have a car with easily unlockable ECU, get it unlocked and do a tune.
