Lude, what's your best timeslip?
I'd like to get the facts before raising the flag....
IMHO, with the mods you have listed, I highly doubt you would've won against a
new E55 (if in fact he was racing)....
However, if it was an older E55 (non-S/C), it may have been possible to edge out an average driver....
They only run mid to low 13's in stock form (still very fast for what they are)....
