Why can't get more hp?

[SpeedWay]

I did dyno for 2009 busa but no more hp?
any suggestion will be great.

What kind of dyno was used? Is your bike stock? If NOT, please list current mods. BTW, welcome.

What did you do between run 1 and run 2? Exhaust? Flash ECU? Anything?

 

[SpeedWay]

Thank you.

i did the run 1 with the same mods i just want to tune the bike
we have the dayno but we don't have the tuner you can just rent the dyno and you do the run by your selflease:

You need to have the bike tuned, not just a pull on the Dyno!

That is what i did i tuned the bike with the Air/fuel ratio to be 13

Two brothers slip one or 4into1?

Those numbers are around what many make stock.
Mine baselined at 165 and is now just over 188 with full exhaust and PcV.

Did you actually tune it or just use the ZFM or sniffer on the dyno for wide open A/F??

 

[isiahstites]

Do you still have the pair valve/emissions? I say your chasing your tail if you tried to tune with those still on the bike.

Also was your run corrected or uncorrected?

I tuned it no ZFM.
I did the run then see what it is come in the chart then i change
the numbers in the map.

As you can see it was lean in the first run then i make it to be 13.2 to 12.8
