I couldn't resist the temptation and finally gave in today. I haven't been able to find anyone who hasnt liked it so far and am fairly certain I will be happy with my purchase. Mike has installed this in a few 325's and he says it really transforms the car. It's the same engine as mine so hopefully I will have equally awesum results.

It's being shipped first class so hopefully it will be in my hands early next week

 

Please post or PM your experience. I have the same car as you and would consider a performance mod if it was worthwhile. Under 300 bucks is fairly inexpensive, so if it's night and day...maybe I'll jump on it as well. Are you installing yourself?

 

I will for sure. I'm going to attempt the install myself, a little nervouse. There are instructions and a video, apparently there is 1 extra step on the e60's, waiting to get the instructions. When I do I will post them. I should have my Power Box around tues-wed, hopefully do the install on the weekend.

 

Got the install instructions, thinking I might get someone else to put it in.

Feel free to shoot me an email at cal@jlevisw.com or PM if you are having any doubts on how to install the BMS Powerbox.

 

Yes it is sweet. And somehow over here, there was an update to increase the low end torque which makes it even sweeter. Feels much more awesome than before. I could never go back to the day before I got it.

 

Enjoy it after you put it in! I forgot to say.

 

I'm sure I will I hear you folks in Singapore have a special map for your climate and high octane gas. Was looking at some of the dyno's yesterday, averaging 20hp with peak of 27hp on some cars. Pretty damn good investment for $300!

I'm pretty sure the NA tune is much tamer but apparently the 325\525 respond really well compared to the 328\528. Time will tell

 

well, we pay a lot more than 300 =) after sales service matters alot especially with the continuous software update. But it makes more of a difference than SB. Good Luck and share your experience after you have done yours =)

 

I was very interested in something like this. Would love to know your experiences with it and how hard the install would be. Looks maybe a little more than I could handle looking at the instructions. Where did you get it from. I am very tempted by this little black box!!!!
