RaceChip is a brilliant possibility to increase the performance of a lot of diesel and fuel driven vehicles with only little effort.
This is yielded by a reasonable mixture of excess performance, increase in torque and fuel savings. The best of all: If your driving behaviour remains the same, the service life of your motor will even be as long as in serial condition.
Proven a thousand times with a long experience: That's RaceChip.

[@RaceChipChiptuning]

Thanks for watching our new Episode! Actually, we kind of messed up the M 340i's tuning run to be honest. By using 3rd to 5th gear as we did for the stock run, we would have probably even been a bit faster... Still almost M4 time! ;)

[@marquesrane2889]

Great video!! I have an F30 B58 w/ mppsk, dinan springs, and I've upgraded my tires to 245/40ZR19s (front) / 265/35ZR19s (rear). I'm looking at the Dinan cold air intake, and may add the JB4. My goal is to be about 425hp / 440 ft/lbs torque. Your video mentions the downpipe install + GTS black. Do you think your install solution of these two items would bring my car to the levels I'm trying to reach?

[@RaceChipChiptuning]

With the first version of the B58 you can reach up to 400 HP (crank) without mods so getting to around 425 HP (also crank, of course) with a down pipe and a RaceChip GTS Black should definitely be possible. However, if you decide to go with our product, please reach out to our technical customer service so they can tell you which setting to use with a modded car.

Numbers only tell part of the story. The M340i is quite a bit faster in stock form than an M4 from a dig race despite the power difference due to the xdrive system. A side by side race tuned vs tuned comparison would have still been interesting. I think the M340i takes both races tbh. Rolling races might be a different story.

[@magoo47]

Hi, I have a Racechip GTS black for my BMW M340i and just wondering if there is a difference between hitting the off button on the phone app and setting 0? Do they both put the car back to stock mapping/tune?

[@vladtudor4447]

@RaceChip , can you make a video on how much difference there is for an 840d like you did with the m340i ? or a bmw 540d on dyno before and after race chip installment ?

[@ericxueAAA]

I am glad the shops are still using M4 as a benchmark for new generation tuning, I bought M4 because f82 is one of the last generation RWD M cars, and the G generation was designed by a previous Citreon designer, I'm not fan of it.

[@gengiz]

If numbers are correct that is an amazing result

[@stingyrogerr]

That m4 was in manual mode shifting early and the gearbox wasnt in the top setting either for fastest shifts? Youre missing about 800 rpm at the top

[@RaceChipChiptuning]

Let me repeat my answer from an older comment which mentioned the same issue: It's actually where the M4 shift flash (in the heads up display) suggests to shift so that's what we went with. We also tried some runs in automatic mode but it didn't make a difference. Since 9,2s with two people in the car is pretty much in the same ballpark as other runs you can find on the internet, we went with that. However, as mentioned in our VoiceOver, with driver only you should be able to get even lower 9 seconds times, maybe even high 8s. But: we drove the M 340i with two people in the car as well so I'm not sure if it would be an actual advantage for the M4. Regarding the shift settings, you are right sir. The M2 mode was set to the second of three modes and we just missed to change it after restarting the car at some point. However, I guess this didn't decrease acceleration significantly. Hope this clarifies things a bit :)

[@andersjensen1499]

Great result - who did the down pipe ? And how much is it ?

[@NickName-nickname]

Hey Guys, thanks for the great video. I’m the lucky owner of an 2022 M340i touring (xDrive) and would like to tune it a bit as well. Wich tuner would you guys prefer (in the Netherlands or Germany). Thanks and keep the content coming 🙏

[@sam.raycars]

After watching half way I have subscribed 💪💙 and thumbed up. Quick question MY22 M340i xD MHT saloon brand new.. Is it worth fitting a down pipe straight away or would you advise run a few thousands miles??? Also fuel economy got me 🤒 what would you say does MPG spikes up?

[@samualadams824]

On the 2nd gen b58 not being a completely different engine I’d have to disagree. It has a reworked head for cooling and a better hpfp are two of the biggest things but all in all has so many other smaller ones that it is a completely different engine with the same name

[@gregsimpson9391]

A wonderful comparison and I share your passion for the B58. I have the M340i touring xdrive and the way this motor responds is just amazing. The sound is classic - I think the single twin scroll turbo 'embedded' close to the intake is the key to that. If I was ever to modify/tune this do you export the packs ? The down pip[e seems a pre-requisite given the gains made just this that.

[@RaceChipChiptuning]

Congrats to your M 340i touring! We ship our products all around the world and you can install them by yourself in a matter of around 15 minutes. Down pipe for the b58 definitely has a bigger effect than for a lot of other engines but even without, you can get to around 460 HP with a tune. For the 480 HP which you saw in the video, the down pipe's mandatory.

[@antoniedavid]

What downpipe is used in the video? Got an m340i and was wondering which specific downpipe you upgraded yours with@@RaceChipChiptuning

[@reddragon1572]

Does it pull well in stock form? Feel torquey?

[@giancarlomessercola4303]

What type of downpipe is installed on this M340i?

[@MrAchilles113]

M4 has 7 heat exchangers to manage higher temps from a higher state of tune. A chip may allow the M340i to make more power, but what about additional cooling and effect on reliability of drivetrain over a few years?

[@sznake]

Just question if you ask me. Including a downpipe and remapping definitely asks for a charge-air cooling system, otherwise it will damage the motor.

The M 340i sounds a little bit better than the previous B58 models even in stock. BMW seems to have invested some work in the sound. Nonetheless, the downpipe still helps a lot, definitely makes a huge difference to stock.

For as far as I know they both use the same b58 engine at different states of tune so I'm going to assume that you just need to get a Performance exhaust or one similar .

[@RaceChipChiptuning]

Engine is b58 in both cases. However, the 540i is a lot quieter in stock than the M 340i so you might wanna think about getting a sports exhaust (best case turbo back but cat back should also help).

Version 2: Deinstall the product including wire harness and it's back to stock for good (which is what most people do before giving the car into service at the dealership)
