My clutch was slipping on the way home from R-Tech

And my spark plugs were causing it to misfire

The clutch has good & bad days, it will need replacing at some point but will have to make do until funds allow. Had the same problem with my old Focus ST straight after a remap.
It's not so bad if I keep the revs up and drive it through the gears. Using the torque in 4th -6th gear is a no-no

the revs just rise and the car tries to keep up. . .
Nick said the standard clutch (when new) will take 320lb/ft but the springs soften over time and it loses it's strength
