I'm about to pull the trigger on a 2020. I'm already working on wheels, tires and suspension. But, let's talk tuning and power. I want to know what you guys think is best. Not necessarily what you did to your car but what would you do if you were to do it all again. Dealers Manufactures are welcome to chime in as well.

There is so many tuning options and I'm not sure what's best. I want something that will give me a lot of ponies obviously but I also want something I can easily remove when I service the car or need to go back to stock after 6 years and need to be able to smog it yearly. Either that or I'm considering buying it out of state so I don't have to worry about it.

I also don't want something too edgy that I'm going to brake the car. Been down that road on a few builds in the past.

I'm pretty much sold on Keller downpipes although I know there is some other good options.

Eventuri Intake

Tunes tunes tunes: BMS, JB4, VF, Evolve, DME, RaceChip, Dinan (do they have one) I'm guessing with the downpipes I'm looking at a stage 2

I want something somewhat simple and yet powerful and reliable. (Am I asking for too much?) lol There is too many options.

My S63 has a simple Renntech piggyback that worked nicely. My Ferrari is full Novitech, E39 was full stage 3 Dinan, Evo was stupid overbuilt with everything possible, sandrail blown LS7, Saleen was first competition package. DBS stock. I clearly like power but I also like reliability for a car like this. I posted some pics for kicks

I would love to hear your thoughts and suggestions.

u want something with alot of ponies, while not risking breaking anything?

sounds like you should stay stock.

lol I know right!

Well, I have had plenty of cars with a lot of ponies that were very reliable and really only one that wasn't. I'm sure there is a happy medium here.

In terms of performance the JB4 is the only tune that offers optional wastegate control and CANbus. You can quick install it with 2 connections in 30 seconds for 10.6s 1/4 mile potential or connect the other connections for 10.2s 1/4 mile potential. Their app is second to none also. Some of the settings like lowering boost in launch mode can be very useful to reducing wear and tear too.

If the car is a lease or under warranty skip the downpipes. Limited gains and they will flag the car for sure with them.

Thanks for the input. The JB4 sounds like it has some nice features for sure. I just didn't want to have to dick with a ton of tweaking and wires. Need something is easy to setup and switch modes easily and be able to take on and off easily before services.

Any idea if downpipes kill a warranty? The main reason I want them is the sound and it seem like most tunes need them for stage two setting. I'm guessing that's a requirement for JB4's 10.2 1/4 mile potential as well?

Eventuri intake, Keller catted downpipes, Akrapovic cat back exhaust, Velos/DME tune. Note I said catted dp’s because it’s gonna be loud with the cat back exhaust added. The catless with cat back exhaust would be too much noise for a car like this (would get old too quick).

Popular to contrary opinion the downpipes don't do much for power, mainly for sound, and most warranties that are voided I hear of are either for flash tuning or downpipe install. As I said avoid them.

BMS ran 10.2 on the factory downpipes. The main thing for the best times is a tuning system capable of running more boost and good race gas fuel.

Yea, I hear ya. In CA I'm asking to get pulled over with catless and the Akropovic cat back. However, I would probably love the sound. My E39 had headers and full pipes all the way back and It sounded like a Nascar and I loved it :P

Okay, you had me confused there for a minute. I just realized that BMS actually makes the JB4 :P

What's your thoughts on the JB4 vs Race Chip or DME?

BTW, I appreciate your time and opinions! Thanks

My dealer just installed my DP's.

RaceChip is the same as BMS Stage1. 2 connection points. It's OK but really limited for this platform since the flashed WGDC tables limit how much boost can be built via this technique. That is why JB4 is able to run so much faster with it's EWG Control and higher maps.

Flash maps are still new and can do things the JB4 can't like adjust exhaust burbles, remove the speed limiter, but once you flash the car goodbye warranty and lease return. So not for everyone. Some of my hardcore customers run both a flash tune and the JB4 on top of it for fine tuning and features.

I didn't realize that. Thanks for the heads up. I thought the flash tunes were actually less invasive and could be flashed back to stock.

I was just reading that a guy bent or threw a rod and he pulled his DME before taking it to the dealer and they still discovered it had been tuned. In this case you're saying the JB4 is much harder or impossible to discover once it's removed?

So are Racechip, EVolve, DME, and VF all flash tunes then?

Thanks

[Fuel-It!]

RaceChip is lower level than JB4 and flash tune. It's the same as this: https://www.burgertuning.com/product...-m5-m6-x5m-x6m

JB4 gives flash like power gains with the ability to be removed without a trace, but can't do everything a flash map can do alone.

680WHP JB4 with RaceGas cannot beat my friends bm3tuning Stage1 E85 Flash F80 M3 LOL

Downpipes does not void warranty (maybe in the west coast) certainly not in the East Coast.
Dealers here rather see a downpipe than a Jb4 any day of the year!

Yea, I'll have to look into the warranty in regards to downpipes. I think it's more of a smog thing really. And yea, that M3 is fast, especially on a rolling start. Just a tad lighter :P

Been down the E85 road and would never do it again. So many issues and hard to get fuel. Only a few places out here, or you can order it to your house. Really not worth it for a daily driver. But, you got to love how cool it runs, the extra horses you can get etc.

what is the camera car in all those videos? i can't really tell

I hear from customers with voided warranty due to downpipes regularly, all around the USA and world. It's second only to customers who have warranty voided from flash tuning. I'm just putting the info out there obviouslly we all race the cars and understand the risks. It's important for those not familiar to know what they are getting in to.

On your friends cars performance do a dragy 1/4 and see where it stacks up. Lots of JB4 cars running 10.2@136mph+. If it's really faster should put down a high 9!

car has plenty of power stock and it can actually put that power down due to its recent 4WD system.. if you want reliability id stick with a simple piggy back like racechip that can be removed in minutes if you have to go to service.. that along with suspension/wheels/other cosmetic accessories and see how you like the car..exhaust wise id go Akra, as long as you're not cat-less you will be fine in OC or LA.. you can always go OEM m-perf exhaust if you prefer to be 100% kosher at the dealer.. if not enough power you can easily remove it and go tons of different directions but then you can likely kiss the warranty goodbye especially if a mechanical issue arises, dealer will gladly blame it on the mods.

[marcvtec]

Give it a good run once you get it, I think you will be surprised by its performance. Then you can easily add a Race chip or bms1, those install in 2 minutes and see how you like that. Then move onward from there if needed .

Did you do both upper and lower? If so, your dealer install catless uppers for you? Because my dealer won’t remove primary cats and don’t know any that will because they could get serious fines.

Yea, I hear ya. I'm going to buy the car with my Montana company so smog isn't an issue. Still curious what BMW would say about downpipes with or without cats. And yea, I agree on the piggy back setup for sure.
