well just got back from the track car still has the same setup no changes, today I ran my best 1/4 mile I did a 13.44 and 105.86, my 60ft was 2.18  

no ones been hitting the track???  

MY 2006 MUSTANG GT AUTO THAT IS STOCK RAN ITS BEST TIME OF 13.4 AT 103 MPH ON A COOL NOV. DAY AROUND 60 DEGREES. HOW EVER IN HOT SUMMER WEATHER 90 DEG IT CONSISTENTLY GOES 13.5 TO 13.7 ALL NIGHT.  

I just got back from the track with my bone stock 2006 GT 5 speed.  I couldn't get into the 13s to save my life.  I have a bunch of 14.1 timeslips at 100-101mph.  Does anyone know the best launch technique for these cars?  I was running the factory tires (w/ 48k miles on them)  and I couldn't launch without heavy spin, bogging or bad wheelhop.  Are my worn out tires my worst problem here? It was a cool night 55-60 degrees.  My best 60 ft time was 2.21, is that respectable for a stocker?  

Ran yesterday, best time was 13.55 at 104 mph.  Cool overcast day.  2005 GT with Steeda CAI and Magnapak exhaust system.  Running General UHP Exclaims, 275/40-18.  Found the best run warming the tires a bit, turned off the traction control, left the tranny in drive and launched at 1600. No spin at the line.  Best 60 was 1.91  Beat a 06 GTO on last run so that made my day.  Next year hoping to get some drag radials and upgrade to 3.73 gears, see if that will get me in the low 13's.
