not for what you have  or need

I concur with Motorhead. Your mods simply don't warrant the necessity or the expense of a fuel curve remapping device.

i have a 01 busa with just yosh slipons for mods
i had it on the dyno and the air fuel ratio was off the chart  started at around 19 then works down to 13 little before redline. i was going to get it remapped with a yosh box but i think ill get a pcii since im planning on getting a full exhaust in the next few months.
is this how it should be with just the slipons?

was the PAIR plugged off?
also you will get a spike from lean to rich at the start of the run

pair is all intact nothing changed except slipons

on the dyno sheet it is 18+ to 14  untill the bike reached around 120mph so seems the low and mid are very lean

If you don't plug off the Pair it won't read A/F correctly
also why mph and not RPM?

so i should do a pair mod with just slipons?
i dont know but the winpep dynojet performance evaluation program  sheet has STD horsepower on the left and MPH on the right and seconds on the bottom.
maybe it was because it was an open house with free dyno runs
i will try to scan the sheet tomorrow
