Were those 60's on stock tires? Anything below a 2.0 on street tires is GREAT. I ran a 12.85 @109.4 with a 2.0 60' with my car at 2,100 ft above sea level with only SL55 complete intake. What were you launching at? What's the track elevation? What was the ambient temp. on your "before" runs? Did you launch in "D" or 1st/autostick? Traction control on? off? All of those (and more) combined have BIG effect on a cars times/traps.
