whats your opinion on the best settings for pc3usb accelerator pump? for a 01 vfr800

I got a pc3usb for my 01 vfr800,loaded a map(2bros and aftermarket air filter) and couldn't tell any difference, so yesterday I found cozi's custom map on vfrdiscussion and it ran really good after that,the only problem I'm still having the low end throttle stumble or unstable.I went with 90% Sensitivity, 15% Fuel Increase, 20 Engine Revolutions.I'll be honest I really don't know how this works or what increase and decrease will do or how to get it right

 

I tried all the downloads online after my mods and was never happy.......... After having it set up on a dyno...... it changed the bike completely ....... really worth the money.
