Either your track is at a high elevation, is greasy, or drivers in the N.W. are terrible! The only time I haven't been able to run mid 13s with my Mach was the time there was water on the starting line. I've only raced one other manual car before my Mach so I'm no expert. Also the last time I went another Macher ran a 13.20. He's 100% stock and guess what? It was his first time ever at a track. The track only had about 50 cars there that day so he was able to hot lap it.
