You are not alone with the first time at the track being a dissapointment. Hell, I remember the first time I went with a basically stock stang I was runnin 15's and 16's all day with the same main problem, traction. Like someone else said, there is no need to do a burnout with your street tires (unless you are forced to go through the waterbox and want to just dry them off, even then, just do a real short burnout). I think when I got my best street-tire 60' I dropped the air pressure by like 8-10 psi and launched at 22-2500. Can't remember too well tho cus I've been usin the MT ET Streets for a while, and if you have two extra rims layin around, I would have to recommend getting a pair of those. If you are going to swap rear tires when you goto the track, don't waste your money on the drag radials, just get ET Streets or ET Drags, slap them on an old set of rims, and then you can launch above 5k without any traction problems, and you will see 1.8 60 ft's or lower. The first time I ran them I was amazed at how much easier it was to launch and I think it was one of the best purchases I ever made for drag racing. Other random advice: Ice the intake, make sure timing is set as high as it can go without pinging, check the TPS, get anyhing unnecessary out of the car before goin to the track (for weight savings), and always try to have only 1 or 2 gallons in your tank when you make runs (weight again). There are also other tricks like using a short belt to bypass your AC and PS, but it looks like your main issue is your launch anyway, your car definately has the HP to make low 13's or even 12's with a good launch.
