Congrats bro!! The 550 is an outstanding automobile -- smooth, powerful and beautiful looking.

Sounds very much like why I got the 550. My thought process was 550 vs M5. I came to the conclusion that there was just no way to get my wife to accept the bigger monthly payment.

Maybe, with a few more clients that are my own and not merely those of my firm.....I'll step up to the F10 M5 in 3 years when my lease expires. That what hopes and dreams and the motivation they inspire are about.

In reading this thred, I am having a lot of trouble believing that, absent some killer mod like a supercharger, a chipped or even heavily modded 535 can keep up with the 500 bhp stock M5. But I freely admit that I am not knowledgable about modding.
I raced a M5. After a certain amount of HP it's traction that makes the big difference. The M5 has a locking differential and wider tires, so it launches better. Also it will get to 150 mph faster because of the extra 100 HP even over a chipped 535.
At 60 mph the M5 is ahead by the front wheels, at 80 mph he's a full car length ahead and walking away from there.
The JB3 is supposed to be faster than my Dinan Stage 2 but don't know by how much.

All this talk about the JB3 chip, but where do you go about buying it? I just Googled it and all I got were the gains from using it. Great. But do you lose a nut paying for one? I heard it was cheaper than a Dinan Stage 2, but that's $2000. What is this, $1983.32?
check n54tech.com or even e90posts....


dyno's are all over that site...

with the new jb3 1.3 beta melter map they just hit 11 sec on a 1/4 mile run....no DP's, not catbacks...no IC....

http://www.n54tech.com/forums/showthread.php?t=3523


current jb3 v1.2 dynos can be found all over the forums mentioned above....

have not seen any tuned n54 engines dyno at 500 hp's....but have seen/read a lot of 400+ ones...


or pm member mike@n54tunning.com as well...


http://forums.e60.net/index.php?showtopic=69841&hl=

the jb3 is an ecu piggyback, if you want something a bit less aggressive and don't wanat to go into the ecu, go with what I have: the JB+ (again info can be found from the above mentioned forums)


Dinan gives you a warranty as least, with the piggyback tunes like the jb3 and procede you run the risk of voiding your warranty as tuner/manipulation codes can be thrown as scanned for when you take your car in for service. But both jb3 and procede owners have posted no codes thrown when scanned via bavarian tool (BT). If you run a tune, mind as well spend a few more extra $ on a BT so you can erase any codes yourself if thrown.

***If your SW version on your e60/535i is pre 29.2, tune with confidence as tuner/manipulation detection software is not on your e60 (like on mine )

That sounds right to me. As speeds increase and aerodynamic drag is the biggest force keeping a car from going faster, bhp is king. Down lower, it all about traction and torque to start out and power to weight ratio until the triple digit speeds. At high speeds, the M5 walks away from your car due to its bhp advantage -- not its traction.

I can't imagine that chipping a TT V6 could result in a 200 bhp gain. That seems to be more in the realm of supercharging, boring the engine out and other dramatic mods.

Still, it's impressive that, with your mods, you can just about run even with a M5 until 60. You must have gotten a big time power gain.

I'm sure you know it's an TT L6 and not a V6. Has BMW ever made a V6?

Yes, my bad for rushing. It is an inline 6 not a V6. I'd defer to more knowledgable members about whether BMW has very made a V6. I'm a 8 cylinder freak anyway.

SW version....hmm. All I know is it was made in April of 2008. Not sure if would also determine software versions.

But yeah, the N54 forums were full of information and was where the Google searches took me earlier. I was all Dinan Stage 2 before, but now I think the price of the JB3 really seems appealing. I don't want to jinx it, but I don't think I'll end up screwing anything up enough to void a warranty. Of course, I'll be taking it out for the services and stuff.
with the build date you are most positively post 29.2

if you don't buy BT tool to delete codes, just try and find someone in your area with one....the regional forums in e90posts can be a good place to find someone....

I've seen members post no codes found when running the jb3 on post 29.2 software (when installed correctly).

Well given that I'd be buying the chip myself and not asking daddy for some dough, I decided as soon as I saw it that I would get everything necessary to save my ass from having to spend more money upgrading and all that kinda jazz. So I will buy the USB device to update it as well. Not sure if I need to buy the "BT tool" but if it's available on the site, I'll definitely get it to save the headache down the road.

Now PnP vs. pinout. What the hell?

I meant that after a certain amount of power, traction comes into play. Even at the end of race whether it's 0-60 or 1/4 mile if you have a better launch the other car first needs to catch up before it can pass, but yes the actual traction part is only when your are coming out of the hole
