Generally speaking, if you spin too much at launch, your 60 foot will increase and so will your trap speed. If you bog too much, your 60 foot will also increase, but your trap speed will decrease.

Missing fourth I am sure cost you a bit, depending on how bad it was. Let's assume, had you hit the gear properly, you might have taken .2 off and added 2 mph to your trap and your just about in the 13's.

If you can pull 2.0's flat on your 60 foot, you will get into the 13's. For each .1 drop in your 60', you will see a .2 decrease in your 1/4 mile. Practise launching (me too) and you should get there.

Also, what altitude is the track? I have messed around with compensation programs, and it seems that for each 1,000 feet in elevation from sea level, will cost you .4 - .5 seconds in the quarter. My track here is at 970 feet, so a 14.0 is like getting a 13.5 - 13.6 in Florida. You need to keep this in mind when comparing your times to others around the country. Of course, is your comparing yourself to others at your track, you will all havethe same handicap.

Weather is a big factor too. If you ran at 90 degrees and 95% humidity and then run again at 70 degrees 75% humidy, you should run .2 - .3 faster. Hot weather tends to made street tires slip also.

If you do not know how to compensate, give me all the data off your slip, including track altitude, temp and barametric pressure when you ran (should be on the ticket) and I can do it for you.
