In my expereince using my p3cars midi to time 0-60 times the best I've gotten was 4.6 bone stock but I got the car in New Jersey and it has always been cold pavement or the tires weren't being as sticky from the cold the PSS are having trouble from a standstill, Stock could do 4.4 no doubt.
With a JB stage 1 and heating the tires up 4.4 a few times but mostly spun to much to get any more improvement or would actually take longer but with 265s and some mods I wouldn't doubt breaking into the high 3 sec range eventually
