Tuning Fuel - Two Bros. Racing vs. Leo Vince


Just got my Dynojet PCV in the mail, but haven't had a chance to install it on my bike yet. I have the software downloaded on my laptop and I have been looking through Marthy's maps and also the Dynojet maps that are available for the FZ6R. Recently dynojet add 2 maps for the Leo Vince exhaust either with or without the DB killer.

One thing I noticed is Dynojet removes a good amount of fuel down low and really doesn't add a lot of fuel in comparison to the Marthy VIPER R6 exhaust, or the Dynojet Two Brothers Racing full exhaust system.

The question I have is are the Two Brothers Racing systems that much more free flowing than the Leo Vince EVO systems? Or should I be a bit leary of the Dynojet LeoVince maps?
