I go over everything you need to know to take your stock 340i and tune it to stage 1 with Bootmod3. Many things I mention also apply to MHD, MG Flasher, and other flash tunes.

What an awesome video man!! Thank you!

[boredrb]

amazing video bro thanks for the info! definitely gonna look into this tune now

[julianrobinson]

Holy shit. It's so crazy to me how with a simple flash you can knock .6 seconds off your 0-60 time. Absolutley nuts

[tavongrant]

Helpful video! Question, what basic maintenance to do first and can you get aggressive burbles with stage 1?

[BrandonFrisco]

very nice content. does your 340 pop and bang at all?

[ProcTech]

Nice to see another B58 in the PDX/Vancouver area. Pretty soon none of these will be stock 😆.

Did you flash the new map yet? Definitely feels like it has more torque than the original Stage 1 93 map.

[evanlundberg]

i also have the digital dash in my 2018. how did you get the speed to show up in the tacometer?

[lammedus]

Hello, thank you fir the vidéo very informative.

I do have a question please: if someone tuned his car, can The dealership know about it and well… require the payment in full of the car or it is just a warranty void ? Thank you.

HI - I just bought a 540i and looking to do a stage 1 with a catted downpipe. More so adding the downpipe for sound benefits and in hopes of maximizing gains with a stage 1 tune. Did you notice a significant increase with stage 2 over the stage 1 + downpipe? Did you ever try MHD? Im thinking the MHD route as stage 1 seems to be a bit more mild then BM3.

Need bigger turbo for top end power, mine doesn't really have anything top end, stock turbo with stage 2+ E30 pulls very hard from 0 to around 130km then it's out of steam, I race against a 2020 stock m3 from a standstill stop and was ahead for up until 120km then he just smoked me onwards

[kennyharvey]

Did you gap the spark plugs? I believe oem are either .028 - .030

[aweburrito]

Do you plan on trying out xdelete? Or is it not worth it cause you won’t be able to put power down

[xander]

Doesn't your car have the 8 speed auto transmission? Just curious as to why you didn't do a trans tune through bm3.

Does the software update issue happen with older generations? I have the analog dash and an earlier version of iDrive

[christianadams]

Does the vsrp down pipe give you a CEL when not tuned?

[tgk_zanchezyt]

Can I keep my 340i on stage 1 tune with a upgraded down pipe, exhaust system, charge pipe and cold air intake

[tgk_zanchezyt]

Could I still stay stage 1 tune on my 340i comfortably if I got a new charge pipe, exhaust and down pipe ?

[wingedhussar]

Let me know how your traction is after the flash.. I'm still on stage 1 93, I personally didn't have any issues but dudes all over the forums are saying the updated maps have traction issues.. The car does feel even faster with the updated map.

stage 2 is designed to be used with the downpipe btw not stage 1. stage 1 is strictly 0 mods
