I can run mid to low 14s all the livelong mothergrabbing day at stock boost, no intercooler, 3" exh and good fuel mods (pump, regulator, new injectors, new filter,) and a 60mm tb. I do have 3.7 lsd and know how to make it work for me though on H rated street tires 215/60/15 and no rear sway bar. My car is heavy, 75 280z with dual ported 10" subs and amps, full heater controls, z32 leather seats(heavy but i cant feel the road through my butt anymore) etc. etc.
