Thanks for that. The twin cam was approx 5% up on power compared to the single cam so that makes sense and I think illustrates the sort of peak power gain you can expect with this type of modification. I'm sure the bike rides much better than standard and for the record I would probably go for a remap or a PC if I still rode a single cam.

I had an Audi A4 with the 130PD engine. A heavy car but once rolling was really quick to drive. But being 2wd, it would easily spin wheels if I needed a quick standing start. The TCS only looked left to right so once both were spinning the car just sat there making me look a twonk. I could see why the more powerful engines were only fitted to the 4WD versions.
I kept it standard which was fortunate when the financial crimps of a nasty divorce forced me to sell it.
As @Giles says a remap on the GSA would be about smooth fuelling. The extra power nice to have but its already pretty quick - I've hardly ever maxed it out.

Ok, that is fair enough, a satisfaction rating. How about a - do you believe you are getting 25-30% more bhp, as stated on the dyno charts?
There are benefits in the remap, so obviously you are going to get a high percentage of people saying they are happy with the end results. All good at the end of the day - but as a GS forum, owners should be aware that there are other options.
Also, with the remap, it is set up to your bike as is - with other options you can change the fuelling to suit when you add or change an exhaust, of change the headers over time - as lots of owners buy used pipes on the forum, it would not make sense to have a remap, add an end can - have another remap, maybe a few months later buy decat pipes, and then remap again. But they may not add any extras and the remap maybe the best option for them. Likewise if you play around with your bike a PC May be the best option.
It is only right that the forum provides all alternatives and we have the widest number of options available, rather than one party with a vested interest. But... Hilltop's dyno set up is very good, of that there is no doubt.

i don't have the time to feed your need for dribble i am so very sorry i did not turn your gs into a s1000rr ,as for the 25-30% yes sum do make that and sum make 3-8% ,well out of the 375 plus bmw's that i have had ,you are the only one that is saying your not happy just for you send me back your ecu by post i will put it back to std and give you a full refund plus your p&p ,and for the comment on what race teams and riders i look after in the racing side that is confidential its the same i do not release the info on bikes that have had a remap to other bodies
.if you had your bike has had a remap after may of 2009 you will not need to come back for a remap if you change the headers or exhaust if your not sure just call me with your reg and i will help you .
have a good one geoff from hilltop motorcycles x

Was it not May 2013 when you tweeked the map to be self learning Geoff?
I for one am delighted with the re-map and the results on mine were not as startling as others. New 90 Aniversary TC went from 83BHP to 98BHP.
That said, it only had 400 miles on and as Geoff said, would still be tight. Id be interested to give it another run when it has a few K miles on it.
I've since added Remus Headers and an Akro can and it goes very well, certainly feels like an 18% improvement to me as well as being significantly smoother and able to pull top gear from below 3K smoothly wheras before it would have been juddering like it was going to fall apart.
I'm pleased.

Well my 2005 1200GS will be remapped this year. Although I do remember saying that last year too 
Whenever there's some bike money saved up, it seems to get spent on something less interesting instead....

yes it was that was the last firmware update i did for the gs to auto AFR but after may 2009 will give a 10% + OR - so that will be ok to change the headers or exhaust
Its the remap option for me now then.
As my new 1200GSA TC is currently in standard spec., I can have it remapped, then add decat headers and Can later, without having another remap...
thats the deal beaker for me, against the PC option.

Me too. I'll be booking sometime late April. Between 12K service and trip abroad late May
Hi Geoff - you did mine 11th May 2013 - can you tell me if that will have the auto AFR?
Cheers.
Mine will be there in the spring too...
Can't wait..

I would say that the ones that make between 3 and 8% are far more believable ;-)
So, Kevmean, have you had yours re-mapped by Geoff? Are you commenting from first hand experience of his work? Just asking...
No I havn't and I do believe all the stories of smoother running and better drivability and possible improved mpg .................. I just do not believe that 25-30% increase on an unmodified normally aspirated petrol engine is possible
My mpg is down from what it was pre-remap but that's because I have 20% more power and torque to play with.... and I do like to play!

Absolutely!!!
BMW have always been famous for over engineering; The K100 was raced at IOM in, I think, 1983 and a turbo was fitted (Luftmeister) to a road going model which had, IIRC, over 250 ponies on a standard crank (other work was obviously done). The design power was 90 ponies. Their bikes are famous for doing mileages akin to starships. In the early days of 'chipping', the chip itself would do little; it would allow further work on inlet and exhaust systems to produce more power. Everything on a bike is now electronic and rather than having to meet strict emission controls as manufacturers have to do, Geoff is free to exploit the potential of the standard engine and it's ancillaries. I have had my 2008 GSA remapped and can categorically state it is worth it. I can say that from a position of authority as I have had it done. Do you question the performance of a set of brake rollers every time you get an MoT? Do you get your own speedo calibrated independently? Or do you trust the manufacturers / suppliers of the equipment? My own power gain was about 24%, and almost triple the torque in some places. I know that because I saw the charts and ride the bike. Anyone reading these posts to decide on whether or not to get it done can believe people who have had it done or believe people that haven't had it done because they don't believe it's possible. The Earth is round; I can't see it, but I trust experts. £350 will by you part of an adventure pannier, or a whole heap of enjoyment.
A K100 was raced at the IOM?? So what, we used to have a production racing class. Also you are comparing a 4 cylinder turbo charged engine with a normally aspirated twin.
Read a lot of the posts - quite a few people who have had it done also question the 25% or whatever power gains. One thing that I find odd is the some make that power comment. Well just about every bloody bike on here is making those gains according to everyone posting their figures, and not 5%.
If you think your bike is 24% up in bhp from standard. Then I'm very happy for you. Crazy that BMW can increase the power by only 13 odd percent and a few owners of the older models with a remap have a quicker but heavier LC - Enjoy your bike.
