    After some searching I couldn't find much about this kit in the UK so here we go.

    Having made the schoolboy error of buying a 2010 E91 only then to find the ECU is encrypted and that the Bluefin unit I used on my previous car (2.0 focus diesel - responded very well to it) was no use I could only see 2 options:

    330D or BMW Performance Power Kit.

    The head won, helped by a significant uplift in annual mileage so off to Snow's in Portsmouth it was to get what on paper is a modest upgrade considering the parts fitted(ECU, intercooler, engine fan).

    First up - Cost. 2hrs labour (fixed price) + parts came to about £1100 - not cheap but looks cheaper than the BMW web site says.

    Fitting: - The dealer had problems programming the new ECU so lets just say it was a good job that it is a fixed price job. They did keep me up to date with what was going on so no complaints about customer service.

    Economy - Three weeks since the upgrade and now about 6-7 mpg better than before.

    Performance - Wow. The car felt flat before and when the dealer said it felt better on a post fit test drive he wasn't lying. At idle it seems a bit less clattery but this is not what the kit is about. Mid range onwards it is now the car that I wanted. As soon as you leave a 30 zone you notice the difference, pulls strongly across the rev range and keeps going, resulting in the need to watch the speedo a bit more closely. Engine is much more flexible and better in every single way. Not sure what it is putting out - but definitely feels so much better and more powerful than official figures. Previously my old car may just embarrass the Beemer - not a hope in hell any more.

    Sumary: If you have a 2009 or earlier car - use a third party remap. If you have a newer car this is highly recommended - you will never get your money back but the smile more than makes up for it.

    Hi, can I ask if you have any part numbers for the parts you ordered? I've been looking into which way to go with my 520D with the same N47 lump as your car. the kit sounds very good.

    cheers mate

    Sorry, Haven't got the individual part numbers. The intercooler appears to basically be the one from a 330D and as I understand it the same goes for the rad fan, which is definitely a lot bigger. Where you might struggle is getting the new ECU and remap that is a key part of the kit.

    I don't think that all N47s are encrypted so hopefully you will be able to get a remap from a third party and then order the intercooler/fan separately if you want it. The dealer was actually quite knowledgeable about what the kit could and couldn't do when I was speaking to them prior to purchase rather than just going straight for the hard sell.

    Hope this helps a bit.

    Hi nadders,

    How are you getting on with this?

    I've just booked mine in to have this fitted in a couple of weeks!

    Cheers,

    Nick

    Hi,

    Where are you having the kit fitted and what is the cost? Have considered this or a tuning box for my 320d.

    Thanks

    We get these 177bhp 2.0d engines to 223-225bhp and 340 ft of torque from just a remap
    ImageUploadedByAutoGuide1415917963.403701.jpg

    The blue line is standard car made 180bhp

    The red line is adjusting the 1 byte limits that hold back the power made 213bhp with no extra fuel or boost added

    The green line is the normal remap made 209bhp

    The black line is the use the byte limiters and the normal remap to make a aggressive remap made 224bhp 340ft

    You don't need to fit a bigger intercooler fan and ecu to get more power from these engines

    Hi Nick,

    Wellsway in Bath are doing it, and cost is enough!

    Luckily, I don't need the uprated torque converter, which the 163 & 177 autos need, which has brought the cost down considerably...

    Have a chat with Tom in service if you're interested, as he was really helpful.

    @ BWchiptune, I fully appreciate that you can get more power than the official kit, but I've seen a lot of posts on various forums about owners of autos (which mine is) having gearbox problems and either going back to standard or getting the map to be a bit less aggressive.

    I'm not implying that there's anything wrong with a third party remap (our other car has one) however not going too far with the power hike, and no warranty problems with this being our main car is more important to me than gobs more power and possible future problems!

    Cheers,

    Nick
