My best time was a 13.2, but my 60' was a 2.3 (terrible) on shitty tires. My best trap speed was 111.5mph. For the boost reading, ambient temperature will also affect what is being read. Difference between winter and summer can be 1.5psi difference. With the SC, it's always a good thing if you can get the boost number to go down without changing pulleys, it means there is less resistance for air going into the engine and there will be more power and less heat.
