Default Tuning for short time

I have alot of my tune dialed in, I am pretty confident in the VE and fueling checked out good with the wideband.

Went to track and I still have a crappy 60ft time( and have not hit my goal of cutting .2 ) ?? Are there any tips that will help my 60ft time?

Where can I look for the timing that is missing?? I think its only getting 21 deg of advance and when I bumped it, it still got pulled to 21??

Burst KR is probably hitting you... there is a table that says if your grams/cyl changes more than X for a given RPM pull x amount of timing.... At launch your grams/cyl changes pretty freaking quick and that table attemtps to keep the timing stable/low to prevent KR. Also you want to check your AFR, at launch to see if your leaning out or insanely rich, that can cause a bog... to work on the launch AFR you adjust your transient fueling tables...
