When my car semi stock (lid, lm2) I also had a "bog" when leaving the the line if I loaded the stock convertor. But I was still running 2.0X's 60's.
IMO you have enough mph to run mid to low 13's, but not the 60'
Let me ask you this, how is the car leaving? spinning hard, or what?
It might be that tune also?
