I have a 2006 550i. I also have a 2002 330ci that I am about to put up for sale. I was wondering if my sprint booster from the e46 would work with my e60. I have googled this and can't find anything. Any help is appreciated.

It should fit as it's a generic product for many BMW models. If it works? Plug it in and find out. In my opinion it's just a hype. If you want to increase throttle response on your 550i go with Dinan Stage 1 for $299 USD + half hour install. You will be pleased with the results as the software does some other "magic" to the ECU to make the car feel more alive.

Thank you I guess I'll try taking it off and putting it in my 550 worst case I'll just sell it, I don't think anyone buying the car will understand what it does. And about the dinan software I was thinking more about ess. But if the dinan does better I'm not against saving some money. I'm going to be supercharging the 550 once I sell the 330 that's why I was leaning towards ess so you can do custom tunes. What is your opinion?

Well, first off, ESS no longer makes S/C's for the e60 550i. I know because I also own a 550i and did my research. I'm guessing, the customer base just wasn't there as opposed to the e60 M5 owners. However, there is a vendor in Europe that sells the kits for around $8500 USD. Some of the guys here have said that it's probably over stock from when they first produced these kits.

Nonetheless, it's a great kit to have but in my opinion too expensive for the horsepower gain. If you do the math you can probably sell your car, add $8500 and buy a decent e60 M5.

About the Dinan tune, you can squeeze out around 40hp and 30tq out of the engine without any bolt-ons. That's the maximum from official tuners. Some guys have done their own maps but my guess is that the life expectancy of the engine will be shortened due to extreme tunes. One example would be the redline threshold. Dinan raises the redline on a 550i with manual transmission by 200RPMs. You can obviously raise the redline to higher numbers but that would hurt the engine in the long run.

It's just some things to consider. In my opinion, it's not worth the hassle to go to extremes with the N62 engine. If you want serious tuning then go with the M5.

Honestly, I have Dinan stage one on my 06 550 and it's just not doing it. I hear the sprintbooster eliminates the dead throttle in the first bit too. I'm looking at getting one soon....

Generally, you won't feel much difference in hp and tq increase as it's only single digits for Stage 1 but throttle response, raised redline and removed limiter (if you take it over 250km/h) make the difference. I am skeptical of the sprintbooster because it's too generic, as in a single unit for all 2001+ BMWs. I would be careful putting it on an e60, especially the 550i with all the electronics present on the car. That's just me though.

It works just fine, had no issues with it but i would strongly avoid using the red option. I turned it off completely for a whole day and you definitely notice a difference... Makes the car feel like it just came out of the factory. ( and this is without sports mode button on)

But to each his own, you'll never know what its like until u try it.

Just letting you know that it did work from the e46 to the e60. You can definitely tell the difference it would be hard driving without it now.

And I was asking about ess tuner not the supercharger kit. I know that they don't make them anymore I emailed them a month or so ago and they said they are developing one now. Their tuner toy can have multiple tunes saved to switch through and you can make custom tunes if I'm not mistaken.

Ok, I misunderstood you. Yes, ESS do have their own software. If I remember correctly they achieve better numbers vs. Dinan, with their Stage 1 tune.
