The car handles it no problem. I drive it like I stole it evey single day. I have never gone into limp mode. This is a 4.3L v8 with 3 turbos. This thing can take it no problem! And if anything does happen simply remove the plug in play and bring to dealer (warranty) durfff

Just like me... Minus the 93 octane lol... Are you using octane boosters or 93 pump? What do you think of Torco Accelerator Octane Booster?

I have used race gas at the track along with torco and believe it or not the car is not any faster. The best results I have gotten at the track/dyno are with 93 octane only. I guess I never gave car time to adjust to race fuel since this is not a real tune.. Anyway. Our cars 2014+ adjust to any and all changes the car makes and adapts. That is why we can crank that dial. Big POWa! |

@eli550,
Hi, I am BMS dealer and I am local to you. Let me know if you still need help in installing them.

I'd be careful with how far you push it. I bought a new '07 N54 335 when they first launched, and everyone was very gung-ho about pushing the turbos on that engine well beyond their specified max PSI with tunes, too. A few years down the road, I don't need to tell you how many blown turbo threads blessed the Internet. Like most mechanically engineered components, the turbos are capable of X PSI, but they're designed for sustained use at something far less. Each one of those turns of the dial is adding more pressure (I'm curious how much - haven't been able to find the info on the BMS site) - many threads on N54tech (Terry @ BMS' own thread there) regarding the danger of pushing the PSI higher than recommended, however. The 11 o'clock position is what appears to be recommended for a stock car (which you'd presumably be running on nothing less than 91 octane). At the 12 o'clock position, the instructions state you should have a high flow exhaust and 93 octane. The 1 o'clock position is reserved for racing fuel. The 2, 3, and 4 o'clock positions aren't even discussed in the instruction manual. So, I can only imagine (and maybe someone here has specifics) that the 3 o'clock position you're using is probably reserved for cars with much more serious modifications. It looks to me, from what I can gather of the BMS documentation, that the "standard" boost to PSI over stock is roughly +2.25 PSI, and +3 PSI is recommended with racing gas mix. You're likely pushing something much higher out at the 3 o'clock position... +5, +6? Who knows, maybe something even more. I have no doubt that'll add some serious performance, but I can only imagine the strain you're putting on those stock components. Lastly, I'm not so sure I'd rely on removing the JB and heading to the dealer for warranty coverage if you blow your turbos. BMW seems to be getting ever-more sophisticated with their on-board diagnostics, and pretty much everything appears to be "logged" these days as far as engine controls. I have no insight to substantiate the claim, but I wouldn't be surprised if the car is capturing information like the turbocharger's boost/PSI levels... so if they're operating well above what the factory settings, and you walk in with collateral damage, it may not be hard to put two-and-two together. Again, I don't know in reality what they may or may not be logging, but I'd only suggest that they're likely clever enough to identify damage done by operating far outside the normal parameters. I'd play it safe and keep it to what Terry recommends. After all, they've done quite a bit of testing of their own product. I wouldn't want to blow up a new 550 only to be denied warranty coverage, either. Ouch!

Ouch I mean 2 Turbos! not 3 lol. Also the car is actully 4.3L not 4.4L. Check out the specs
I understand where you are coming from.. but when you car is leased and your tune is simple 30 seconds remove and install. I see no reason why you cant crank it! It is undetectable. Also, This engine has been in BMW's lineup since the early 90s. I think they know what they are doing if they continue to use it to this day! with some minor modifications of course lol Its a ROCK!

The N63TU is also new as of 2012, and is only based upon the N63, which was new as of 2008. Prior to that, all BMW V8's were naturally aspirated. The N54, introduced with the 335 in 2007, was the first turbocharged engine BMW had made in decades. So, yes BMW has been making V8's for some time now, but the N63/N63TU, as a turbocharged engine, is a whole different ball of wax. Case in point? BMW's bread-and-butter has been the inline-6 for decades. But the N54 had more problems than any BMW I-6 in history. Understandably, it was BMW's entrance back into turbocharging - a grand experiment. In fact, it drew the attention of a class action lawsuit (which was won) against BMW. The N55 quickly "corrected" much of what was wrong with the N54. While clearly BMW's direction is turbocharging, I'd also keep in mind that they haven't been at it very long now. And as seen with the N54, past reliability of any naturally aspirated engine isn't an indication of how reliable the turbocharged engines will be. All in all, I don't think the N63 was winning any awards for reliability - and while I hope the N63TU will be better in that department (as I own one!), time will tell. So, my only point here really is that you're pushing the engine well beyond what it was designed-for, and then additionally you're pushing it beyond what the tune manufacturer (BMS) is recommending... probably by a significant factor. After all, at 3 o'clock, you're 4 clicks beyond the recommended setting, or nearly a 100% increase over the recommended setting assuming the clicks are linearly dialing-in boost. I wouldn't count on the engine being a "rock" as a countermeasure, either - as it's not been the reputation of the N63, and likely won't be the reputation of the N63TU either. I also wouldn't count on your behavior being "undetectable" to BMW. Again, I don't know this for sure, but they seem to log a LOT of information on engine performance. I would have a hard time believing they're not logging information about the amount of boost being produced by the turbos, especially if they're also logging misfire events, etc. And if the engine was damaged (e.g. you blow your turbos), would they not correlate the unnaturally high levels of boost and deduce you were using a tune? I don't know. It's a big risk that could cost you a lot of money if you're on the wrong side of that gamble. In any case, I understand your enthusiasm, and it sounds like you're having a complete blast with it - that's a complete monster at those hp/tq ratings! Best of luck with it!

Oh and I finally installed it, didn't understand how easy it would be because most tunes seem much more complicated. Man it's fast! But I want faster, can I put it at 1 o'clock setting with 91 octane gas?

BMS' guide says the 1 o'clock position shouldn't be used unless you're using a race gas mix minimum (no other hardware required), whereas the 12 o'clock position recommends 93 AND high flow exhaust as minimum. If you're only on 91 I'd stick to 11 o'clock (default) - it's probably another 2.25 PSI of boost, which is still significant. I'm guessing it's conservative enough where Terry feels the potential for damage is minimal. I think ARC is living proof, though, that you can set it much higher potentially without consequence... or maybe not near-term consequences, at least. Just all depends on how much risk you're willing to take.

Out of curiosity, what station was it? I don't think there's anything local here that goes remotely that high... most I've seen is 94.

Lol. So much excitement. She does pull hard, very hard. I wrote BMS and inquired since I use 93 octane but still have the factory exhaust. They recommend the dial to be set to 11 o'clock. Installation couldn't be simpler. From the reading I've done, you gain 80HP at the crank, so roughly low 60's RWHP. I ordered the 1/4" flexible tubing (see pic) to cover up the wires for more of an OEM look.

Bro crank the dial! Don't Liston to BMS. Crank it to 1 o'clock and let it ride bro! Then you will feel the speed! If you do full 104 octane crank the dial ALL THE WAY.
Keep in kind that the tune we are using for our cars is a Box for Mini coopers. These was no R&D done. There was nothing. BMS was ducking around and found that it could be used for our cars and BAm! Crank it! |
