Ive got to be honest and say that this is starting to sound somewhat suspect to me.
I have no experience of Hilltop and in the main id rather stay out of threads that slate particular businesses, however.....
Each standard bike dyno I've seen/read about on the XR, including those ran in the USA which has renowned worse fuel, all come in over 150bhp ,
This video 1.50 in for example:
Or this Italian video:
Even akrapovics main website dyno graph shows substantially more as a stock bike, if anybody would try to suggest a huge power increase by switching exhausts it would be them
Now i appreciate all bikes are different, but for somebody to tell me that the bike started with 130bhp RW and then they managed to get 160 RW out of it screams of data fudging/rigging to me.
Unless there was something initially wrong with your bike, or indeed you swapped out the exhaust, air box and a whole range of other stuff in between runs, over a 20% increase is simply out of this world.
Im not about to start on the man as i don't know him, and he may very well have tuned certain race teams bikes, hell he may even be a really nice bloke.
But just think about it, over a 20% power increase?
Somethings not right with that.
He may very well have mapped the bike a little better and yes its probably better than it was previously, but with such an improvement in power to the RW you would, without question, notice a HUGE difference..... it just sounds way too much.... or too little to start with
Each to their own and if you're happy thats great, you paid the money and if the bike feels better thats all good.
But I'm sorry, the math doesn't stack up with what you've been told, rightly or wrongly i get the feeling he's over egging his work on these standard bikes a little too much
