You raised doubt about the the honesty of the Hilltop business and the result of their work. You've done it again in this post despite people posting paper proof of what has been achieved. You have no idea of their business so you wont know that they don't need the business from BMW remaps at all . . . it's a sideline to their main business which is race bikes. If they never remapped another R9T/GS again it's not going to have a significant effect on their business so why would they lie ?
Had you criticised them after having had their product on your bike then fine - go ahead, spout all you like but you haven't, you were suggesting the gains were unlikely - despite not having experienced their product. The Internet is full of people like you who hide behind your keyboard making snide suggestions about products and people . . . you're the detritus of forums like this which are based on people sharing their experiences - not their dubious opinions because they've chosen a different route.
So I'd suggest you go to Hilltop, sample their product and if you're not happy, get a refund. (Or get a refund anyway) That way you can tell us what you think of their product without casting doubt on printouts which show what people are feeling when they ride the bikes. You also need to do some reading and learning to understand what a struggle BMW face in Europe to meet EU3 and EU4 emissions regs with a 1200cc air cooled twin. You obviously have no idea about this.
Hero ? My heros are much closer to home.
Like others, I express my skepticism that 25% power gains can be achieved through ECU tweaks. A number of other posters have said the same in this thread, from talking to their local tuning companies, as I also found, from talking to my local tuning company. Yet it appears that it's just me who comes in for flak from you, Steve... Was it the sarcastic humour of my initial post that has upset you so much?
Your initial attempt to suggest I'd made an incorrect decision installing the PC - that the "gains" were within the tolerance of the dyno and that I probably hadn't gained anything, made me chuckle because it was clear you thought power gain was the be all and end all. I later pointed you to my earlier post confirming that I didn't believe there was any power gain, but that the bike was a lot more ridable and enjoyable (Oh, and the Remus downpipe was chosen because it looks nice

). Unless of course you do know it's about smoothness and rideability, but that wouldn't have helped the aim of your post...
Your response could have been something along the lines of "
Whilst I can see how one might think such gains are unrealistic, you're wrong and this is why..." (as clearly you own, and have read, many books on the subject) - you see, a chance to share your experience... But you don't share your knowledge and explain to us. You choose simply to refer to me as "detritus", "makng snide comments", "hiding behind a keyboard", screaming that I don't know what I'm talking about... Can you see the irony of your post now, Steve?
If you want to provide a good explanation how the gains are achieved (another poster made a constructive point that timing was also modified - maybe get Hilltop to submit a little piece?), it would be a great learning point for lots of us on, but if it's just "
I've read a book, you haven't, shut it!" along with a few repeated, cliche'd personal insults, then you must accept that some of us will still be thinking of Alien Bogey's magic wand...
