I don't see anything in the log that would make the car fall flat on its face and stutter...although your load drop from 450 to 399 relatively quickly but your boost doesnt follow that... not sure what is going on there...
Your throttle is closing up twice in the third gear pull.. but I am not sure if your tuner is using throttle to control the load? If they are it could be that... but your LTFT and STFT are within reason... and you ARE holding boost a bit above desired... but not much.. a couple kpa...
Your RPMs are not smooth however.. not sure what is going on there? Could just be how the data is being recorded but its not a smooth acceleration..
Small amount KR but not much... I am surprised you are getting any KR with OAR sitting at -.30...
Are you recording to a laptop? or through the SCT device?
Why don't you email Brad? You sig says you are tuned by him.. not sure why you don't speak to him directly...
Additionally... your sig also says you are spraying meth... your logs suggests otherwise.. no reduction in IAT's, the STFT+LTFT don't show the added fuel, and you shouldn't be seeing ANY KR at that spark and boost if you are spraying... IMHO..
