It's not going to help much on a car without a mechanical diff. Out of interest, what happens after 3000rpm to all that lovely torque? Talking about the difference between the FR and Cupra to get back on topic, whilst you mention the peak figure, what about the Cupra's torque spread, its at peak from 1700-5800rpm, which means you don't have to do an impression of someone rowing a boat when making brisk progress.
I'm not sure you'll bait many more Cupra drivers, as they're probably out enjoying their cars instead of sat working out how to improve their MPG, have you tried streamlining?
Wait, are you saying you torque steer round corners??!
No but torque steering is exciting, right?
I enjoy my car and my bank balance at the end of the month, you enjoy yours
