Just installed the BoosterPlug on my 9T. I had one on my R1200GSA too.

On the 9T there is a noticeable difference in how smoothly the bike runs and how it seems to rev more eagerly.

Now I can install the Remus headers on the weekend :D

I am very interested in hearing your report on the headers/boosterplug combo. A video of the sound would be great too but no pressure or anything:)

Toying with this idea as well. Any thoughts on how BMW would treat this in regard of warranty? I could see much of an argument why this might cause trouble, but never know with BMW...

I guess you could always take it out before going to the dealer- how much work is the installation? Need to lift the tank, right?

It would greatly depend on your dealer and your relationship with them. If you've ever argued with an insurance company after an accident, that's pretty much how the dealer/BMW corporate warranty repair dialogue goes. If you had serious engine trouble while under warranty and had a booster plug installed, you'd have to be pretty tight with your dealer to have them go to bat for you with BMW. I have a pretty good relationship with my dealer, but still wouldn't perform this mod inside of the warranty period.

Yes, takes 30 mins to install. No way I'm waiting 3 years until my warranty expires to install headers. The BP helps the engine run more smoothly with a richer mix AFR... it is not a performance mod.

If installing catless headers, a richer AFR is a must-do, else the engine will be running too lean. They are already too lean from factory to meet emission standards.

Dealer relationship is key. For example, if you removed your exhaust flapper it could void engine warranty.

Where did you plug it in? I am guessing you bought the 1150 one?

Looks like it plugs into an injector?:confused:
No, it piggybacks onto the air intake plug on the airbox. There is a ton of info on the site.

People also shouldn't forget that (in the states anyway), the dealer has to prove that your modification caused whatever your trying to get fixed under warranty to break. So if the whole engine goes kaput and you deleted your exhaust flapper, they can't claim the flapper delete did it (since it's absence is not capable of killing a engine) and void your warranty.

So my boosterplug showed up. I (without a service manual) made an attempt at lifting the tank, took the obvious front 2 bolts out and the long skinny one under the seat, the tank moved a little but there is resistance (I assumed it was fuel lines). I put it back, figured it wasn't worth messing anything up.

What do you have to do to get to the air box? Seems like the tank has to lift a good deal.

Tank lift procedure:

I only did the initial lift, not the 2nd full lift

So just the rear stop flipped up and the front of the tank resting on a piece of wood?
Yeah, but if you have big hands you may need more space to get to the air box sensor, in which case do the full lift.

I got it installed without having to raise it all the way even though I have big hands. No way I was going to disconnect the fuel lines, too lazy for that. I ziptied the sensor line down the snorkel and the senor is sitting in clean air on the front of it.

Headers just showed up today(thought they were lost for good, fedex isn't so bad after all) but I haven't installed them, even still the boosterplug makes a noticeable difference in what I would call "grunt". Engine is definitely happier!

Cool. BP rocks!
With the Remus headers, on re-install, watch the silencer doesn't rub against the rear tyre. For some reason the header change the alignment slightly.

VERY excited to see how this works. I am planning to go one step below straight pipe on this bike (after owning two silent K-bikes you'd understand).
