There is more useable HP lurking in those engines unless there is a port , airflow restriction, camming problem, air resonance, valve spring, problem waiting to be fixed. Something is still stopping the air getting i at high revs.
    For the AFR to get rich towards redline is normal, in any engine, I believe it is using the fuel as cooling at those high loads.
    A leaner mix will burn hotter and increase the engine temperature a lot at high RPM's and the risk of damaging or even failing your engine is high, so by adding a bit more fuel on top you have a cooler combustion reducing engine temperature, increase the life of your engine, and lose a little power.

    So you are not seeing a lack of air due to restrictions, you see the engine mapping doing exactly what it is supposed to do.

    I had mine Dyno tuned a couple of weeks. I have a K&N filter, DNA airbox lid, Power commander FC fitted and a Mivv GP high level exhaust. Blue is a map downloaded from PC web site but for a different exhaust.

    Where did you buy it from? I see the Dynojet USA site has Model FC22065 for Yamaha FZ-07 listed at $249 plus carriage etc, but Dynojet UK does not even have a listing!
    The curves look good and AFR is excellent, right through the rev range. Have you got a graph of how the curves looked before the PCFC was fitted? How long did it take you to fit it?

    Hi Scimm77, I got the FC from ebay, here's the link..

    CENTRALINA POWER COMMANDER DYNOJET EFC22065 YAMAHA MT-07 2014 2015 | eBay

    I didn't get the bike Dyno'd before adding the FC but it feels soo much more torquey and responsive I also get around 5/8MPG more now + I know it's running correctly. Well worth the money.

    Dyno'd my bike yesterday!

    Have been riding with the Acra titan, stock air filter and stock ecu for more than a year now and decided to take the next step.

    So i ordered a DNA stage2 filter and a PC5 and booked a day on the dyno

    Red Is with db-killer in and stock air filter and stock ecu
    68,51hp / 64,07Nm (47,26Ft/lb)

    Green Is with db-killer out and DNA stage2 and full map.
    70,35hp / 68,05Nm (50,19Ft/lb)

    First Dyno run, standard bike-mappning-jpg

    I’m very happy with the result!
    And most of all I’m happy with the new smooth throttle response. Its amazing!

    Went to Dynotech at Bramley recently and spent about 4 hours fitting a DNA kit, Power Commander V and some dyno runs.

    Also tried it with the cat out and although it made a little more power (half an hp) it added to the noise and as fueling was better with it in we put it back in.

    So only about 1.5 horsepower gained at peak BUT about 10% gain between approx 4500 and 7500 rpm and now have 70+ bhp between 7200 and 9700.

    If I want to ride in a quieter mode it's only 1 hp down with the baffle in.

    Have also gained almost 4.5 ft/lb of torque (52.84 ft/lb) with more torque from 4000 to 7700 than previous max (48.45 ft/lb).

    Here are the graphs to help explain.
