Just had my '11 X5 35i tuned at Cobb Tuning

I've been fixing up the car since I got it. New water pump/thermostat, oil filter housing gasket, oil pan gasket, plugs, new Zimmerman/Textar brakes all around - Koni FSDs are en route. After taking care of the major stuff, time for a bit of fun. I've got no mods - running completely stock on about 93k miles. Went down to Cobb Tuning in Plano after picking up an AccessPort V3. The OTS map was a little better than stock, but nothing to write home about. They explained to me that the OTS map is still running the stock ~9PSI.

They tuned me for 17PSI conservatively. On the drive in, I averaged about 20MPG. On the drive back, doing the same speed, I got 23.5. Very happy all around, and decent power out of the N55, especially considering AWD power losses.

Not going to start a tuning war - Just showing that there's plenty of power left on the table even in stock form, and how a good dyno tune can bring out a bit of that extra performance without having to go straight to bolt-ons, especially if you're going for a compromise vehicle like I am (good performance/good economy). Cheers!

Test drove another X5 35i owner's car with a JB4. Difference was night and day. He agreed after driving my car. Mine pulls so much harder, and is noticeably smoother.

So, he's gonna sell the JB4 and get a dyno tune/AccessPort.

And now, the car needs an ER charge pipe. Getting a slight leak at it, at higher RPMs. Getting that fixed on Monday.

I was under the impression that there wasn't a JB4 for the N55 E70. Only a BMS stage 1. If true, perhaps that explains the difference

Correct. Confirmed from ANDO@BMS. I sent him a email weeks ago and he replies saying there's no upgrade performance for the x5 3.5i except stage1 & Intake. Sucks

when you say "conservative"....how much more do you think they could have pushed out of it?

Stock 9psi to 17psi sounds AMAZING. But I think it's unsafe for long term. Maybe 9 to 13,14psi, but shiiit if the n55 can handle 17psi sign me up. It's kinda scary tho that's a big gain

And is 9psi really the stock level?

Well, the guy told me it was a JB4. He could've been mistaken and it could very well be a BMS Stage 1. Either way, it wasn't close.

Boost tapers at higher RPMs, and I'm not running a lot of timing. Most of the aggressive N55 tunes are running 19PSI, which is where the stock turbo's efficiency falls off a cliff. Since I plan on keeping the car long-term, we dialed it back to 17PSI. The engine/stock turbo is more than fine at 17PSI. Nothing scary about it.

The car was tuned by Cobb Tuning's best tuner, out of Plano on their Mustang dyno - This wasn't an inexperienced no-name shop, mail-in tune or a piggyback.

The car's also putting down those numbers with 95k miles on the clock after a fresh intake cleaning, new plugs, and all new fluids.

They've tuned lots of N55s at Cobb. Mine was the first X5 35i though. So far, loving the hell out of it. But, I've got a charge pipe leak that rears its head at higher RPMs now. ER CP just arrived in the mail today and is going on with a set of Koni FSDs.

Here's my 0-60 with just romping on it, manually shifting at 5800-6200. No brake launching or anything, just sport mode and romping on it, hence the terrible 60ft.

DAMMIT, now I gotta spend more money. Your x5 must feel amazing, I'm kinda bored with my setup already
BMS stage1 juicebox, BMS intake, sprint booster throttle control. Congrats on your setup?.

question:
-does it have to be dyno'd or Cobb has maps for us already?
- how long did you wait for the Cobb, noticed the site is saying its on back order
-can boost be controlled thru the Cobb?

Thanks

1) The lower line IS the Cobb OTS map for the N55. Stock would be even lower. Pro Tuning Freaks and Cobb can both have you do logs and send them in for tunes, though a dyno tune is a bit quicker and can yield a better tune.
2) They had it in stock. Look on the 1/3 forums for any N55 AP - All V3 N55 APs are the same and compatible with the X5 35i - BUT CALL COBB FIRST with your VIN to make sure that your VIN is supported. They only support up to some early 2012 models.
3) The boost is part of the map. If you have a low boost map, then yes. I like it because I can select a valet map or anti-theft map if I like, then I can lock the AP away. That being said, for driving, I have a single map which has boost as a map parameter that varies according to other variables. The cool thing is, the ECU is always 100% in control. It's the safest you can get.

I am looking to buy the Cobb tune as well. I run the JB3 right now. Cobb website lists 9-10 weeks backorder... Many people confuse JB3 stage 1 with JB4 since JB4 is hugely popular with the 1/3 series crowds. Stock N55 boost is 7-10 psi. I think the engine targets a HP/TQ number hence the difference in max boost. The JB3 ups the boost by 3 psi. Cobb has ability to up the boost more which is why I want to try Cobb now. Once they have it back in stock, they will have another X5 customer. I just need to figure out why my car is throwing engine malfunction codes again... 2C86 and 2C58. If Cobb has the tune in stock in Texas, I would love to drive down there and get it tuned by them if I was closer.

Like I said before, call Cobb and give them your VIN to make sure it's compatible, then just go ahead and buy someone's N55 V3 AP on one of the 1 or 3 series forums if they say it'll work. Or just wait. They're cheaper used though. Just make sure they've been unmarried. And no, the engine targets aren't done by expected HP/TQ outputs. It's based on a lot of parameters that yield a given amount of performance as a result, however.

As for your errors, try removing the JB3 and see if it goes away. It could be a wiring thing -- one more reason why I prefer going the AP route. No wiring, and no modifying signals to the ECU. You can likely give Neil a call at Cobb Plano and inquire about tuning via email. ProTuningFreaks also offers this service.

JUST A RANT.

X5 was in service for 2days and I got a 2016 x3 3.5i. I'll tell you we have some fat over weight ass "SAV's". This x3 was so light you can actually feel the power of the 3.5 not to mention the sound from stock exhaust is pretty nice n loud humming. Thinking about swapping my 11 for a 14ish lci x6 CPO.
Take care. Don't mind me lol just took a perc

I considered the new X3, but with the tune, my X5's quicker. No AP is available for the X3. And if I really want relatively light and tossable, I've got my 135i.

Speaking of light & tossable, the x3 feels like it will flip with enough hard swerving. Just got the X5 back and I'm glad I did. I Missed it for these days

Your 11 most certainly will take an AP.

With the current hardware setup, maybe another 10WHP, 10-15ft-lbs with more aggressive timing and running the turbo to 19psi or so.

In order to safely get more power, I'd need to do a charge pipe (doing it), catless or high flow catted down pipe (might do it) and bigger FMIC. VRSF is working on one that might work and I've offered to test fit on an E70. After that, it's upgraded turbo (Pure Stage 2).

I doubt I'll take the car that far, but the N55 seems pretty reliable, from what I've seen, up to ~400WHP.

Yep, the Pure Stage 2 N55 turbo will fit on the X5. It's just that most people who want performance out of the X5 go for the V8 or the X5M. I wanted to have my cake and eat it too with performance and decent economy without the complexity of the diesel.
