It drives way better at all speeds Just get it!

I had to bitch and whine quite a bit about the retrofit but ended up getting the to install it for $400. That includes installation of the cable and the programming. Still pricey but I'm always listening to music in the car so I might as well have it sound good

Now my only complaint with the car is the comfort of the drivers seat. I sat in a 5GT when I dropped the car off today, now those seats are comfy and the interior is to die for! Too bad the car looks so ugly on the outside.

 

yes it does pick up quicker, like a sprintbooster. + about 6whp.

 

BTW, since you are in Toronto Mike from N54 tuning will most likely install it for free I'm not sure how often he is on here but know he frequents E90 Post quite a bit

 

Most dyno's I have seen are more like 10-16 hp. There is no way I only picked up 6 ponies the car is way quicker.

 

It "feels" quicker because of the throttle response being more, well responsive lol.

For example lets suppose if you push the pedal when the car its stock @ a 45 degree angle in 3 seconds, the rpms would be at 2.

The throttle response being more responsive means, that now at the same angle at the same time instead of being at 2 it would be at 4 rpms.

thus you getting the "feel" of more hp. It lets you peel out a lot more, which is why ppl also think it gives them more hp and torque than what is posted. lol.

 

I used to have a sprint booster, the gains are noticible even on map 7 which is just the tune on Once you hit 35 mp\h or so you notice the increase in power.

 

Burgertuning site says it works for 2007+ 530i. Can i use it on my 2004 530i?

 

If in doubt give them a call, thats how I found out they had one for my car.

 

It depends on your built date I think early built uses M54 engine this BMS Powerbox will work on N52 ... so find out which engine type you have.

 

Boo...no fitment for my M54.
