You said Air/Fuel, Does that mean you have one of those gauges that are a light show and not a wideband? If so, disregard the light show and get a real wideband.

His profile says he has a wideband.

OP- can you get a log of when this happens? This would be helpful.
What AFR does it go to?

my wideband say lean so i'm fully lean. or above 20.AFR

Unless your saying when actually launch it and are moving and aren't using a Anti lag....

It's perfectly normal for it to go lean while on your on the 2-step it's cutting fuel an the ignition to keep you Rpms where where you want...

You can post a log of launching or holding you Two step to be sure if you would like...
