Burger Tuning N55 Stage 1 Tune - 2011 X5 3.5i

I acquired a 2011 X5 with a 3L engine a few months back, and just by sheer coincidence, I walked into a deal that allowed me to install and document the install process of the N55 Stage 1 tune from Burger Tuning. Initially, the wiring harness was missing a piece of hardware, and Terry Burger was terrific to work with. I ended up receiving the missing hardware a week ago, and last night, I managed to install the tune. The entire process took about 30 ~ 40 minutes. Everything is SO much easier the second time around. I took my sweet time to ziptie everything in place, so it took a little longer.

I only got a chance to take her out for a quick drive, but WOW. There is no turbo lag and the extra torque down low is very noticeable. As soon as you step on the gas, the X just moves forward. Granted, it's not as fast as the M3, but the drive-ability is definitely improved. The throttle response (aside from the slow auto tranny) is comparable to the E46 M3 which has six individual throttle bodies and is infamous for great throttle response.

After a few miles, I switched over to manual shifting. Up high, the engine really screams and it's definitely faster when the revs are high.

Overall, it's an excellent mod especially for the price. The install isn't too bad, and I will create a more detailed install doc with a long term review.

I had to take the piggyback off the car due to the fact the car was due for inspection I, an oil change and a new alarm module. All in all, I drove around with the X5 is stock mode for a few weeks. Immediately, it felt the car lacked a lot of power in all the gears. Today, I re-installed the piggyback. WOW, it's amazing what the difference is.

The engine just feel so much more responsive without the turbo lag! Over the last few months, I've never had a check engine light, and the fuel consumption wasn't really any higher. Overall, I'll have to give this mod a full 5 stars. To everyone that is on the fence, this is really good value for your money. The extra torque is very noticeable, and compared to modifying the M3 for power, $400 is a bargain to get 30 HP and 50 FT/LBs of torque

Is this figure based an X5 without the OEM M Performance tune (..like a 335is has) or an X5 with the tune?

What is it doing? Mine comes off when I insert my screw driver into the hole at the end the elbow. It helps when you rotate the elbow when the screw driver inserted.

What is supposed to happen? I insert the screwdriver and try to rotate but nothing happens. I'm guessing that plastic piece will separate so the elbow will come off but nothing.
