I just got a great deal on black Friday with Bren and made a road trip out of it. You can send your ECU down to Bren and they can flash it and send it back to you. The instructions are on their website. I just wanted to do it in person and have them dyno the bike as well. And as an aside, with the factory alarm taking up space, I would have had to remove the alarm in order to install the rapid bike unit. I am happy with Bren, but I am sure I would have been happy with rapid bike as well.

Thanks for the feedback. I still need to consider pros and cons on those three choices and this has helped.

When ioriginally got my bike, I thought I'd be happy with just the slip on. Then eventually I wanted a full exhaust. From there I just wanted what was the most cost efficient way to maximize the fueling to compensate for the full exhaust. But after researching, I realised that I had already spent a lot of money on the bike, and I didn't want to cheap out on anything, and to me Bren Tuning wasnt cheap, but offered the most gains, and I clearly wasn't disappointing the results.

Thats hard to say. Initially when i got the Brentune flash for the first time, I noticed a big difference with the flash, even running as rich as it was. However, I had a 2011 R1 prior to this bike and I installed a PCV, velocity stacks, and had the bike dynotuned and I got 12 hp out of those modifications. It made 161 hp on the dyno. Obviously these bikes are running much more power out the gate so with a PCV and dynotune, Im sure you will be more than happy. I guess the question you would have to answer is, how much do you want to spend and are you willing to deal with some possible hiccups.

I will say, it would be much easier to just install a PCV and get a dynotune... zero hiccups with that route. Maybe do some research and see how much power these bikes are making with the PCV setup alone and go from there.

I'm very happy with the final product of the Brentune and PCV but it did come with some hiccups and back and forth stuff. Fortunately, it all was taken care of over the winter so I didnt skip a beat.

I believe the main thing is to get rid of the heavy CAT and its exhaust restrictions. Evidently, some fuel/air adjustment across the RPM range is required to balance the engine's performance following the CAT removal. I also believe the original headers are well-engineered by BMW, and aside from a Titanium weight advantage, full exhaust replacement may not be necessary, in my opinion. This is where your experiences help me decide. Thanks!

Yes, the problem is I am not able to have Dyno-tunning services in my country, so I'm looking for a plug-and-play arrangement (maybe even using fueling maps from proven Dyno tests in similar conditions). Yet, the idea of a constant adaptive process offered by RapidBike EVO is tempting. OTOH, I'm not familiarized enough with the Brentune alternative yet, which also offers advantages.

In fact, I would need something constantly adapting to the circumstances as well as not needing Dyno runs with the bike. What exactly does the Bren Tune approach offers? I apoligize for the nagging, I just need to decide soon.

It seems after reading more about the topic, my best approach would be to install the PCV and add the Auto Tune. That way, I can ensure gradual optimization of the mapping over time without the need for a dyno session. Does this make any sense? Thanks for any suggestions.

Might suggest the SFM to maximize the upper fuel range as well. Had mine done at Attack Performance and Iím very pleased with the results.
