Why am I so slow

Thanks for all your help, I did get rid of the off line stumble with more tuning. I was running way rich at idle.I do need a higher stall and will be fixing that issue. I did find where my 60' time was going. I took that car out and did some on the street tuning. got on it and left about 70' of rubber on the ground. didnt believe it so I had my brother get out of the car while I did it again to confirm. Yes i was spinning that bad, but there was no sign of it. no sound from the tires, the cars rear wouldn't slide out from under, nothin. It only have stock suspension but wieght tranfer seems good, and it launches straight as can be. Just when I get on it and the car sound stong,but seemed slow i was spinning the crap out of my tires,and not knowing. Lookin into a pair slick, then will return to the track for better time slip.
