Had mine done a while back and completely transforms the bike, no flat spots at all, runs smoothly across the entire range and pulls like a train.. Best £250 i've spent!!
Surprised no one has posted try using the search,quite a few threads on Hill Top
2017 GSA LC. TI Akra headers and BMW Akra end can.
Tell me Hilltop doesn't get more power.
Hi Phil
The negative spike at approx. 4800rpm on the BHP & torque lines... was there an explanation or supposition given for this occurrence?

I would guess there are tests performed in that range regarding fuel/emissions - no one in their right mine would want a graph like that, and it's not the first one I've seen with that dip either.
That's euro 4 regs for you. Euro 3 regs gave better fuelling and didn't have that big dip.
No... but you really don't notice it at all. Power delivery is silky smooth and noticeably higher
My bike has super smooth on/off throttle, the dip in torque after 5000rpm is noticable if you roll on from that figure. the bikes seem to vary a bit in detail of the power/torque curves but not by much, mine is slightly smoother than the above. The most noticable improvements are smoother running everywhere, much more torque in the lower/mid range and a couple of extra mpg, probably because of this, and you can normally pull a gear higher than before.
Just had mine done today - 25/09/17 - 100 miles back in mixed weather and traffic, seams smoother for the most part, less judder at low revs in low gears, just feels nicer to ride. Looking at the graphs it's about a 10% increase for both torque and power across the majority of the range on my bike. No real info. on MPG as traffic was terrible, so not a good comparison as I spent a lot of time a 50mph - but at a guestimate I'd say it's got slightly better, certainly not any worse. Who would believe you can get almost 90mpg sitting on the M6 at 50mph on cruise for nearly 20 miles?

Very similar results to me, dynamic mode is now very lively![]()
Proves I need new tyres![]()
