Yes this is common , I ran a 14 my first time at the track and some of it was me , this was pre nitrous and DR's so If I pull my head out of my ass I hope for a low 13???? I to have raced the 12 sec car and won??? It's the need to be better at something like mentioned above, I dont care if your faster , maybe one day I'll catch you, maybe not? All in all i find it humrous, I met a guy about 8 months ago with less mods than me , same year z, he ran a 12.7??? according to him! ran him beat him!
