well no one can answer that man, even if someone had an identical car, with everything yours had and a comparable driver it would be off. Tolerance differences while manufacturing...who knows maybe the drivers mood, can all ammount to advantages and disadvantages.

but, if you want someone to just yell out something,... give more details. Tranny, any head work? what kit? turbo? wtc.

my guess 16-15 on auto.
