    My co-worker just got a COBB AP/Bren tuning PRO tune for his 2015 Subaru WRX w/manual tranny. His only mods are muffler delete and COBB/Bren Tuning PRO tune. My car is a '13 550i with JB stage 1 tune. He's never dyno'd his car but we ran from a 40- 90mph roll and it was dead even until we neared 100mph and I started to walk off before we let up.
    He sent his logs to Bren Tuning on that run, he was running 35* of timing and they had to revise his tune down to 29* of timing.

    They leave a lot of dust, but work great. I can use the first pulloff at Sonoma Raceway no problem, usually that's reserved for Civics going 80mph through the traps. No fade that I've noticed, but I don't road race so this is just highway/twisty roads/drag racing. I did have to bed them in twice before they felt good. FWIW I have them on Centric Premium blanks

    On a recent thread of yours you said you pulled on stock coyotes. If that's the case you should easily pull on a tune only wrx as they are slower than stock gt's.
    I know because I've repeatedly pulled on my friends cobb tune only wrx from a roll with my JB1 only GTI... My GT stang is a lot quicker than my GTI from any speed.

    A stock 550i is a low 13 second car, if he beat a coyote he probably beat the driver.

    The WRX was running a very aggressive tune, which has since been dialed down to safe levels and I had an incorrect e85 mix. This past weekend, I played with a LS3 SS on the highway and put a car on him to 120mph and played with another 5.0, these were from high rolls 65+.

    also, im stage 1 tuned which is good for mid -high 12s.

    I remember seeing a stock 550i inching a JB4 335i and those are high 12’s low 13’s. I thought a 550i with a piggy only was in the low/mid 12’s? Is yours a N63TU?

    Sounds like fun times OP.

    Is the 550i really a low 13 car? I've ran a couple over the last few years an pulled them both by at least a few cars up to 120ish.

    Edit: Ok after looking it up it must have been the older models I ran.

    Most reviews I've seen put them in the 13.2-13.4 range. They're pretty heavy cars (4400lbs), I think the 8spd auto is whats keeping them in this range. 445hp/480tq according to BMW North America.

    For comparison sake, a e39 m5 which was just at the tip of 4000lbs and made 394hp, was also good for 13.2 1/4's.

    Looks like you have the 6.1 Charger from your sig. You must have ran some E60 550s.

    Yes, they are heavy and they feel heavy.

    2014+ 550s has the N63tu engines and run 12.4-12.6 stock (445hp/480tq) 0-60 in 4.2
    2011-2013 550s has the N63 engine and run 13.1-13.4 stock (400hp/450tq) 0-60 in 4.6

    Ive outran an E39 M5 already in my F10, from a dig it was brutal



    N63TU differences

    • Adoption of VANOS from the N55 engine
    • New cylinder head cover with adapted crankcase ventilation

    • Adapted crankshaft
    • Chain drive with modified guide rails and an extruded chain with 142 elements.

    Oil supply
    • Pendulum slide cell pump with small overall width
    • Eight individual oil spray nozzles for piston crown cooling.

    Cooling
    • Integration of the two engine control units in the low-temperature circuit and cooling over the back panel with cooling pipe
    • Expansion tank under the left side wall with separate filling hopper.

    Intake and exhaust emission systems
    • Adaptation of the manifold for the air intake duct due to new geometry of the cylinder head cover
    • Use of the hot film air mass meter 7
    • Adoption of the charge air temperature and intake-manifold pressure sensor from the N20 engine
    • Exhaust turbocharger with new compressor and modified wastegate valves
    • Discontinuation of the blow-off valves.

    Vacuum system
    • Two-stage vacuum pump with new arrangement of the bolt connection
    • Vacuum reservoir for the wastegate valves in the V-area of the engine.

    Fuel preparation
    • Use of the known high-pressure injection with injectors and high pressure pump HDP5

    The E60 550i's are slightly slower but still in the ball park.


    I guess I didn't notice the earlier F10 550i's had less power (400hp and 440tq), I can't find any times for the outgoing F10 with 445hp and 480tq.

    Here is a 13.4 from road and track

    http://www.roadandtrack.com/new-cars/road-tests/reviews/a16735/2011-bmw-550i/

    and a 13.1 from car and driver

    http://www.caranddriver.com/reviews/2011-bmw-550i-instrumented-test

    BMW says the xDrive model does 0-60 in 4.3, so I guess the newer cars could be high 12 second cars?

    Now I hate I passed up the opportunity to run one a couple weekends ago that was driving pretty spiritedly, It looked like a newer car but I'm not BMW enthusiast so not sure.
