However, once VF34 turbo kicks in around 3500-3700rpm, that's where car pulls like a freight train and keeps pulling well above 100mph unlike TD04 that dies around after 80mph...
I agree, the pull of the VF39 (for me) is well worth the torque lost on the bottom end. But truthfully, how many times are u are WOT at 1500 rpms???
