I read a lot of topics about Ivan's flash. A lot of good reviews. Some people write that even the exhaust sound gets better.About engine braking. I did experiments this summer. Engine braking is greatly affected by the enrichment of the fuel mixture. If you make the mixture richer, the muffler stops popping and the bike slows down the engine much worse. If you make the mixture poorer, on the contrary, there is engine braking and the muffler starts to pop. If I understand correctly, Ivan just prescribed a richer mixture in the ECU. You can adjust the engine braking by using the mixture screws on the injector. This will make the engine braking more or less as you like. I'll probably do a flash of Ivan since everyone is praising it so much. I want to improve my bike somehow.Ivans is the one mod that provided the biggest performance increase for mine. No other single mod comes close. It removed all the factory constraints and also unleashed higher rpm's. I get better fuel mileage now, and the annoying engine braking is very significantly reduced. Vibration is also significantly reduced, I can even see in my rear view mirrors. Plus I have zero backfiring even on hard deceleration. My acceleration out of twisties is improved. This mod imo is a no-brainer.

I had always planned to go 110ci but realized I don't need it. I smile just fine!
