yeah you did pretty good, i am sure once the track warms up and they get some more rubber down you will see a lot better times.
there are a lot of factors that effect your times such as temps, humidity, altitude, track conditions, your tires, fuel, tune, track prep just to name a few. Not one single factor will make or break your times (of course unless you have an extreme of one such as 110 degree temps or 100 percent humidity) lol.
When do you think you will get your tune?
I bet the 60' king distantpulse can help you get your 60' times down to legendary levels on street tires
