Avoid BHP UK for motorcycle tuning - Save Your Money
I purchased BHP UK's ECU Flasher and tuning service for my 2020 Kawasaki H2 SX SE. After a month of dealing with them, I can honestly say this was £648 wasted.
Before everything, I must say that the manager didn't offer to fix the map AFR as I wanted, and also to give money back bcs he is not able to tune below 3000. Now the full story.
Problems started immediately - we agreed on a £50 customs invoice, they never sent it, and I ended up paying £149 (30% more). I sent them my exact setup: IXIL slip-on, K&N filter, Dominator decat, no exhaust valve. The main reason I bought this service was to fix the jerking at 2000-3000 RPM during city riding. This is a well-known H2 SX issue. When I tested their map, the jerking was still there. Their response? "We do not tune below 3000 RPM." They literally admitted they cannot fix the problem I paid them to solve.
I asked for a revision. The second map was worse - rough idle, jerky throttle, terrible quick shifter. They told me to use the first map, basically admitting failure. I spent €50 on professional dyno testing which showed AFR of 12.8 - leaner than the safe 12.3-12.5 range for a supercharged engine. They also didn't configure the map for my setup despite me providing all details upfront.
When I asked basic questions about what they modified (standard practice for any tuner), everything was vague "trade secrets." When I showed dyno evidence, the manager became defensive and accused me of trying to steal their map. Absurd. I'm just an owner trying to verify the map won't damage my €20,000 motorcycle.
I requested a refund per their published policy and offered to return the device. Response: "I will not entertain any refund request from you." They refuse to honor their own guarantee despite clear evidence of defective work.
Bottom line: £648 for a tune that doesn't fix the stated problem, has questionable safety, wasn't configured correctly, and comes with hostile service. The only positive was +15 HP. Save yourself the money and frustration.
EDIT: I got money back via Charback from Mastercard. So big WIN for me and proof that I was right.
For Cal - You were not able to tune bellow 3000 what I asked and fix AFR, end of story mate. Good luck with tuning!!

Hi Marko, We always welcome feedback both positive & negative. We strive to deliver a 5 star service for all our customers and feedback is the best way to know what we're getting right and what needs improving.
With yourself it very quickly became evident that you were not a genuine customer and are in fact associated with a tuner and were simply trying to reverse engineer and copy our mapping. Its one thing to buy our Flasher and attempt to copy our maps but then to try to return our products is another. To come and leave a negative review is quite simply stretching the boundaries of audacity.
