N54一直有个Performance Package, 3k多，额外多加一个散热器，换个更大功率的散热风扇，然后发动机output多个10%左右。
现在搞了个cheap version, 600$做个software update, max boost增加了一点，从300hp上到320, tq变成327左右。
The BMW Performance Power Kits Provide More Exhilarating Performance and Excitement for The Ultimate Driving Machine
19.09.2011
New Power Kits for 135i and 335i Models
Woodcliff Lake, NJ – September 19, 2011….Now, more invigorating horsepower and torque, is available with two new power kits bring crisp stimulating performance to the Ultimate Driving Machine. BMW 135i and 335i Models can now be retrofitted at BMW centers or via the Port Installation Program to an unprecedented level of performance. These new Power Kits ensure that new car buyers and current owners are in for that extra thrill beyond the outstanding performance that can already be realized with these exciting vehicles.
Version 1 Power Kit: [Review and More Details HERE] Performance-Optimized Engine Software. This version of the Power Kit was first introduced on the 335i BMW Performance Edition model (announced in July, 2011). Available for all Model Year 135i and 335i vehicles. Also available for X6 vehicles produced up to 04/2010.
Version 2 Power Kit: Same engine performance software as Version 1, plus an Auxiliary Water Cooler and an Enhanced Radiator Fan to reduce the higher thermal stresses on the engine during extreme driving. Available for all Model Year 135i and 335i vehicles.
To coincide with this exciting announcement of two new Power Kit versions, BMW is offering a special introductory price on all Power Kits from now until the end of 2011!
Special pricing for the Version 1 Power Kit is $599 MSRP* (including Power Kits for X6 Models).
Special pricing for the Version 2 Power Kit is $1,199 MSRP* (this price does not include the additional air ducts or other components that may be needed to install the Version 2 Power Kit).
*Not including installation. Contact your local BMW center for final pricing.
Power Kit Highlights:
Horsepower is increased to 320hp (20hp increase).
Torque is increased to 332 lb-ft (when equipped with an automatic transmission) and 317 lb-ft (when equipped with a manual or DCT transmission).
Faster acceleration:
0.2 seconds faster than the standard 335i model from 0 mph to 60 mph.
0.5 seconds faster than the standard 335i model from 50 mph to 75 mph.
“Exhaust burble” sound during engine overrun conditions (new feature).
Specially developed in-house by BMW engineers to work with 135i and 335i vehicles.
Vehicles retain the original emission certification.
Vehicles maintain the original fuel efficiency ratings.
The vehicle’s original BMW Limited Warranty is not affected.
Note: Power Kits should only be installed on 135i and 335i vehicles equipped with option code S840 (increased top speed limiter – which includes an additional oil cooler).
BMW Power Kits are the only form of “tuning kits” approved and covered under BMW of North America’s limited warranty. Power Kits are designed and tested by BMW engineers to provide the highest power increase without sacrificing reliability.

Original info/announcement on 335i Performance Edition Model and Retrofit Kit

A few words & first impressions:
1. Price - $1,200 installed, including tax. I was able to negotiate $100 off. So $1,300 for others. Part came to $985, install was $250 (dealer dependent), plus sales tax.
a. Given that the only other part I ever had retrofitted before was an alarm on my 2007 e90 ($299 from factory, $750 retrofitted) I can appreciate that there will be a price difference between the factory & retrofits.
b. Since I had considered the full PPK (Hardware + Software) and was quoted over $2,500, although disappointed that it wasn't close to the factory $550, I was happy that it was less than 1/2 the cost of the full PPK
c. Price change - As of 9/19/11 and for the remainder of 2011 the kit will be reduced to $599. My dealer is working with me and BMW NA to recover the difference in price of the part since I purchased within 2 weeks of the price change.
First Impressions - disclaimer - I'm the first one to admit that you can't really appreciate differences in vehicles just by "feeling it". This is truly anecdotal, and given that I'm not interested in ever putting my car on a dyno take that into consideration when reading my review.
a. I didn't realize I ever had turbo lag. I now have immediate power at very low RPMs. This was the first noticeable difference from stock. I can honestly say I definitely don't have any turbo lag, although I didn't think I ever had any - boy I was wrong.
b. Ground was wet, so didn't go crazy.
c. The gains were definitely noticeable, especially with the low end torque. I have an XI so wheelspin isn't typical, but in DTC mode I was able to get some wheelspin. I have yet to play around with DSC completely disabled.
d. I agree with the other post thus far, there is no "throw you back in your seat" moment, but again, it was wet and sloppy out so I didn't really push it to its limits.
e. The difference was also noticeable when accelerating between 40 & 80mph. I was about 10mph faster than I expected to be when I looked down at the speedometer after a brisk acceleration.
Second Impressions - 2 weeks after install -
1. You definitely "get used" to the tune. After about 2 weeks of daily driving, and over 500 miles, I can honestly say you don't really realize it's there anymore
a. Then you put your foot to the floor. There seems to be a sweet spot just around 3,000 RPM where you can get thrusted back in your seat.
b. If you're just doing daily driving in D mode, you may not be able to appreciate it at all.
2. Gas Mileage - Maybe it was the route, or maybe I was driving consciously, or maybe it was the tune - I did a 240 mile trip and for the first time in 20,000 miles I averaged more than 500 miles to the tank.
a. When they say gas mileage is unaffected, I can honestly agree (under normal driving circumstances). That is of course unless you're pushing it to the limit and well, you'll get 12mpg. If you are driving in a more "spirited" manner, but not pushing its limits I'd say gas mileage is slightly diminished by at most 25 miles/tank.
Summary -
The PPK Retrofit is a fast, easy, and warrantee-d way to give your 335 a little performance boost. For 20hp and 33tq, I agree that this is a good value if you were to build your vehicle with the "Performance Edition Kit". It is as close to a 335is as you can get from the factory, obviously minus the DCT and over boost.
As a retrofit - I'd only really recommend it to owners. I spent a pretty penny on my vehicle, and an even prettier penny on the extended warranty for 7 years.
If you lease your vehicle, save your bucks and buy one of the AM tunes. You can't go wrong with $300-700 for up to 60-70hp. My motto though is "you get what you pay for" and I'm sure none of the vendors would step up to the plate if your vehicle was damaged as a result of their tune (except Dinan, but that's another story). From what I read they all have fantastic customer support, but I would never expect them to say "yeah, sounds like my tune did that to your car, we'll fix it" - especially if BMWNA blames it on the tune.
If you own your vehicle, this is a great way to get a little bit more performance, and the security that BMW will back its product through the extent of the warranty. I'm sure it will retain its value dollar for dollar out of the factory, $0.50/$1 if you get the retrofit.
Overall I'm happy with my decision. But then again people value different things. I'd rather pay more and have this covered the full 7 years of my warranty, than have a problem with a cheaper solution that provides more performance gains. You may want the product that gives you the best $$ per hp.
Hope this helped. Bottom line for me is that this should be the way the 335 performs right out of the factory, and it's a bit disappointing to have to pay for it.
