hestitant on hard acceleration when cold

[don17]

having issues with hesitation when trying to accelerate hard after changing gears when cold, or depressing the pedal fully. usually fine around 50 degrees celcius, feels like a fueling issue/cut, maybe over fueling? any help much appreciated. log attached

Do you have a log from when it is cold?, it is 85C in that log.  The lambda is way richer than target, not sure if there is something wrong with the lambda or it really is that rich but it certainly wont drive well if it is actually that bad.  

Your accel fuel settings also look a bit out of place to me, you have no accel fuel at all in that log.  Usually the deadband will be 0.2-0.6% on a G4+, and cold correction will usually be much higher.
