If we are taking about on the road straight line performance then we most certainly have to include gearbox, final drive, differential, etc.
JB4 in a 135 does 0-60 in what...low 4s? Seems obvious that this will outperform the stock 1M 0-60 given the times we have seen (4.5 best I believe). Once a software tune is available for the 1M it will certainly be quicker to 60 then the 135 as the power is better directed to the pavement.
