2020 V4 Arrow+Filter running issues

I originally fitted a full akra on my bike, I got the exhaust second hand so I did not have a akro flash to go with it. First I had a termi flash that created a massive flatspot at 7 but pulled like a beast up top. I wasn't happy and looked at all the dyne charts posted around the world and saw that most people had the flat spot on the curves that they posted but no one complained ( could not work it out)
I then got a brentune flash which deff made it better at 7 but the bike was extremely rich on top , I asked brentune to correct it but they didn't( short story).
I then looked at our Australian super bikes dyne charts and saw that they have no flat spots with termis and fitted a set of termis and ran the termi ump again. Flat spot completely gone and finally I am loving the power delivery power every where.
So the problem is not in the map its in the pipes

I wouldn't say that proves the problem is the pipes. I would say you didn't have a proper tune for the exhaust you had. When you had a termi tune with a termi exhaust, it was good.

all the other dyne graphs posted with the flat spot also not tuned right? I had the brentune for the akro? I would say the pipes are the biggest part of th problem

Yes, because all the tunes you are talking about are canned tunes. Once you can start comparing proper dyno tunes, I would place money that you will not see a flat spot with any of the exhausts.

are you running Termi slip-ons or full systm?

i just talked to Brentuning. they said the Akro is the best systemt they've tested, followed by Termi Uscites and then SC Project S1-GP full system.

The issue from what it seems is that flashing the tune to the ecu is the challenge. There seems to be something different for when Ducati went to the 2020 in regards to this. So thats what they are working through on my bike. I will keep you guys posted as it develops.

I had a full akro and have a full termi. Brentune told me the same thing when I asked them but at that stage I didn't believe anything they told me. On our dynos the termi makes more.

cool. do you have an opinion on what's the best of currently available options based on your experience?
