    BMS (Burger Tuning) F10 550xi N63 V8tune all wheel drive before/after Mustang dyno numbers - + 67 all wheel horsepower

    Great dyno numbers here for an all wheel drive F10 550xi equipped with the N63 4.4 liter V8 twin turbo motor. The owner got a piggyback tune from BMS (Burger Tuning) which retails for a very reasonable $379. What does $379 get you? How about an increase of 67 all wheel horsepower and 74 pound-feet of all wheel torque? Very impressive gains and keep in mind these are at all four wheels on a Mustang dyno which generally reads more conservatively than a Dynojet.

    The baseline for the car was 354.9 horsepower at all four wheels. Stage I with the default settings put down 390 at all four wheels. Taking Stage I and adding an additional 4 PSI of boost takes output to 421.5 at the wheels. A gain of 66.6 but let's just round it to 67 wheel horsepower.

    Check out the dyno graph below.

    Saw this on another forum - his car is running strong for sure.

    Does anyone know why the +4 psi setting requires 100oct? That should put peak boost around 14psi which is right where my Dinan tune is at. I believe minimum octane required for Dinan is 91oct.

    Speculation... but I assume 100octane was to satisfy an oem like ignition curve whereas dinan runs a more conservative curve that allows 91 octane.

    The Stage1 is intended for +2.25psi and pump gas. By pushing boost higher you need higher octane to support the timing curve used. I've not looked at Dinan's tuning so I do not know what boost & timing curves they run.

    Makes sense - does Stage 1 actively remap/adjust the timing (e.g. CPS offsetting) or is it changed by the DME reacting to other inputs that are changed?

    Here's what Dinan stage 2 looks like:

    Could you run the extra 4psi with E85 or E85 blend instead of 100oct at $9.00 a gallon?

    Or this from Dinan...their software starts at a "reasonable" $4099.00 and the goodies and upgrades beyond the software get more expensive from there. Kudos to Terry for offering solid tunes that normal folks can afford to buy.

    "If you’ve ever owned a BMW, you’ve probably pined for some Dinan upgrades. The company, founded by Steve Dinan in 1979, occupies the sort of space that AMG once did for Mercedes, before it was brought in-house — while Dinan isn’t officially affiliated with BMW, the Germans clearly don’t hate what he’s doing. And what he’s doing is taking fast BMWs and making them faster.
    Amidst the chaos of Pebble Beach, I get a chance to head out for a drive with Dinan in his 550xi S2, an all-wheel-drive 5-series with reworked suspension and brakes. And also more power; instead of the stock 550’s 400 hp, the Dinan car makes 508 horses and a staggering 584 lb-ft of torque. The speed limiter is jettisoned, giving the car a claimed top speed of more than 200 mph. How far away are the Bonneville Salt Flats, anyway?
    Even with a turbocharged V-8, adding that much power involves more than an ECU reflash. Dinan hardware includes larger intercoolers, a new exhaust and a cleverly reworked intake. Where the stock 550 uses diagonal chassis braces at the front corners of the engine bay, Dinan installs hollow braces that act as a secondary pathway for air to enter the intake. He says the system increases flow by 20 percent.

    I’m honestly not going to be able to test the suspension upgrades in the environs of Pebble Beach — 17-Mile Drive is a poor venue for seeking max g-forces — but I do get plenty of chances to dip into the throttle and feel that wave of torque at work. With all-wheel-drive, the 550xi S2 just lays down the power and crushes you back in the seat. It already feels, to me, much like what you’d expect out of an AWD M5. But if you want to get even closer to that ideal, you could opt for the S3. That one includes bigger turbos and makes 542 hp, which would be close to an M5, if BMW didn’t thoroughly sandbag its factory horsepower numbers (an M5 is really more like 600 hp).
    While the 550xi is an interesting exercise in “What if?” I’m kind of more interested in just shooting the bull with Steve Dinan as we drive. This guy knows BMWs on a level that’s probably deeper than anyone outside the factory. Really, he is his own secondary factory at this point. “We’re more like a small car company than a tuner,” he says. “We have 70 people, and a lot of them handle the programming.” Indeed, in the car I’m driving, the motor, transmission and suspension are all reprogrammed, and all work together flawlessly. “When I started, it was easy for a few guys to modify cars. But I don’t know that I could start a company like this now.”
    I want to know, given his experience, which BMWs he thinks are best. Critics, myself included, tend to view older BMWs like the E39 M5 through rose-colored glasses. I used to have an E36 M3, and I still contend that BMW steering never got any better than that. But Dinan, engineer that he is, can be pretty dispassionate about old cars. “By the time they come out with a new model, I’ve already torn the old one down so many times that I know exactly what they fixed the next time around,” he says. He enjoyed the E39 in its day—“That was a great car for us,” he says, but he’s onto new things. You can’t get too nostalgic when there are 2014 M5s out there, waiting to become 750-hp M5s.
    As far as his clientele, the increasingly insane performance of factory BMWs hasn’t hampered Dinan’s influx of customers. A stock M5 is arguably overpowered as it is, but people want more. “The M car customers are our customers too,” Dinan says. “They’re prequalified on two fronts — they want power and they’ve got money to spend.”
    Thus Dinan isn’t competing with BMW’s M division; he’s taking it places that it won’t go for years to come. Consider, for instance, an all-wheel-drive M5. BMW will probably build one. And you could wait. But for $16,291, the cost of the S2 package, the future is now."

    just for general information, there was an all Dinan modded out 550xi and it limped almost every run, and those runs it didnt limp, it went dog$#@! slow.. the owner left all pissed off

    where-as the BMS modded car was doing well, dont recall actual numbers, but is the car referenced here, and no limps throughout the day.. BMS FTW! Click here to enlarge

    Terry BMS - the torque curve is a bit weird

    Is that a peculiarity of the 550i... dips 3500-4000 stock and rises again

    I want to point out that Dinan can charge a premium because of the name, their warranty, and also because they have more of the ecu cracked than anyone short of Alpina.

    So far every Dinan car that came out to run me from stage 2-5 all have been Running close to stock times... after further investigation we found out all cars got the tune from same dealer in NJ Prestige... After calling Dinan it was found out the tunes have not been installed or updated on the cars since 2012... The stage 5 car is constantly in the shop because of drive train issues.
