BMS 600hp S55 Package

Anyone ever seen or heard from others on this package found on BMS site?

https://burgertuning.com/collections...hp-s55-package

I was going to get the Jb4 tune when I noticed this.. Curious if anything feels said HP numbers are legit with this package. They unfortunately didn't post any dyno stats.

BMS is legit and I assume those numbers are at the crank not the wheels. Buy it, dyno it and report back my dude.

Flash tune is better than JB4; the JB4 is a piggyback and you should want to avoid them. There's enough threads in here as to why.

Solid package that covers the basics. You can add in a JB4 E85 MHD back end flash map for those OK with the flash risks and really unlock the power on straight E85 too.

It's not a matter of which is better as the JB4 is a tuning tool that works with the factory or any flash map you want to run. There a few things that can only be done via flash tuning but there are also more risks involved. For many the JB4 and its huge proven reliable power gains are a great way to go. And BMS has free flash maps for those who decide to jump in to flashing.

I own just about most of the parts included in the package, so I'd say buy with confidence from BMS! 600hp is definitely a realistic figure on 93 octane, or ACN91 pump gas combined with E30 fuel mix just on Map 2 alone. FWIW, my old F80 produced 508whp on a dynojet with ACN91/E30 fuel mix, with the only other addition on top of the JB4 being kittyless DPs.

670+ hp is easily attainable with 100% E85 fuel when stacked with the free BMS E85 BEF. The BEF can be safely flashed via BM3 for those who prefer the web-based platform. I've also submitted a feature request with PTF for better BMS BEF compatibility with their platform.

Stay away from that intercooler they offer with it. And the only part of that "package" that adds any power is the JB4.

Also, you can get more power than that with a BM3 only and blending some e85.

Looks kinda legit. Wish the intake worked without needing a tune. Damn thing threw the CEL every 3-5 days. Curious to see how the car dyno's and feels.

I have the BMS intakes with only BMS S1 and have zero issues with CEL. I've read where the MAF sensors not being fully seated can cause the light tho. It did take a bit of wiggling those and threading each screw in a few turns at a time to get them to seat all the way.

It's the same files but I've never loaded with BM3 so I'm not 100% sure on the steps vs loading with MHD.

It's sort of an ECU software variance things. Most cars don't throw a code others might. It's not just the BMS intake it's all of the intakes it's just that BMS is the most popular so you get the most feedback on it posted.

I'm running JB4 with stock motor. Currently on map1 with +40whp. Overall improved the powerband throughout the rpm range. I can run more aggressive maps once I get more bolt-ons and higher octane gas/e85 through the JB4.

" the piggyback myth " facts : with JB4 you save to pay 2 or 3 CUSTOM TUNE to your favorite tunner for each fuel type and map change while you are driving via your mobile.
N54, N55, B58, S55, S63 .... qwickest and faster with MHD/BM3 bef and JB4 on top.

I saw several customers that pays $1800 for custom tune their F90 M5 worst perform than others just with JB4 in map2 and 93 octane.

Thats odd you had that, I did the BMS intake months before downpipes and tune, with absolutely zero issues.

Backend flash changes amount of boost requested, engine timing, fuel, etc.


JB4 spoofs sensors to make engine request extra few pounds of boost. What else does JB4 do?

It makes no sense to me how a backend flash stacked with a JB4 has a positive performance effect (but I know it is true, I have read it + seen it as well, like you are saying)

Timing, fuel, boost. What else is getting changed in backend flash, and what else is getting spoofed by JB4?

A BEF doesn't necessarily increase boost values (this is where the JB4 comes in), but you can run increased load targets, fuel scalars, ignition advanced, VANOS changes, and etc.

The JB4 is more than just a boost controller. For the S55, it can function as a meth controller with various safety triggers, PI controller, integration with E85 content reader, data logger, and more. In essence, think of the JB4 as a highly advanced boost controller unit with a plethora of features. Several high horsepower M3s and M4s have a JB4 installed for a reason.

With a BEF in place the JB4 isn't spoofing anything. It lets you dynamically adjust your load target, and then that load target hits whatever levels for timing and AFR are programmed in the flash. With on the fly load adjustments you have a lot more tuning flexibility, like having load vary based on ethanol content, water/meth flow, port injection flow, safety engine conditions (like afr in either bank, fuel trims too high in either bank or too much variance, etc).

Then on top of that you get an awesome wireless app, in dash gauges for boost, timing, meth flow, etc, and free maps.

I installed, reinstalled around a dozen times. Could never get it to work. I thought about maybe applying some silicone. 🤷🏻*♂️
