If it was me personally, the first modification i would get is a tune, and a logging tool. And keep up with maintenance. Maintenance is key to longevity.

I'd argue the charge pipe with BOV is a bit better at managing pressure than the stock BPVs. So maybe no for "performance' as in going faster, but it's probably better for the mechanism's performance generally.

Apparently my dad is sayingg that tuning is legal but it won't pass smog. You Mr.E92 are saying that I should get it tuned and add a logging tool. I honestly don't know what a logging tool is but I know what a tune is. I heard MHD is pretty good for the Bmw 335i. I really do wanna tune it just cause it might help with shifting lag or delay. Thing is if I do Tune, I don't know what to do and how to install codes unless there are already codes. Could you explain what a Tune is and what a logging tune is. Will it help with the shift lag? If not what does a Tune do to the 335i?

COuld you step by step explain how to install MHD and XHP trans tune. I watched videos and they are all confusing cause they are skipping some important parts. Im not gonna tune or add parts yet and drive stock for a while just because I'm saving money rn so I could get VRSF exhaust, New aluminum chargepipe, and an intercooler which will probably cost me around 2.5 k maybe, and also adding the tunes. When they ask for a tuning license does it mean you actually need a tuning license to tune in Cali or is it just a tuning license for the app itself so that you could get their packages and transfer that data to the car?. I'm honestly so confused rn
