Help with tuning drag car

If anyone has experience tuning the Projection please email me.
We can discuss my specs and fuel maps. All my drag race data and 60' times say that the car should run high 11s. I'm not sure if my fuel map is off (too rich). My Autochart software has a analyze feature and when I use this on the data captures from my 1/4 mi runs it makes no recommendations to the fuel map. Maybe it is simply a matter of getting the car to launch at the right RPM. I cannot footbrake too high because the car starts to creep and I red light.

I 60' 1.6X consistantly (on Nitto Drag radials!) however my MPH is too low to get into the 11s. My data says that I am losing too much rpm between shifts (the dreaded 1-2 shift of the 700r4) my shift point overall also seems to be to low 5400-5500. Any advice

my best run has been a 12.49 @ 105

Next mod skinnies and slicks.

Just from my exerience I would say you're probably running lean in the upper rpm range. Do you shift yourself or do you let the tranny shift itself? I always shift myself if I want to go fast, let tranny shift if I'm just driving around.
