Given the changes time to recalibrate the ECU after a power-down (batt disconnect) and re connect. Fookin ell - major noticeable smoothness and loads more grunt - timing is able to advance due to EGR, which has improved power and torque feel. Pulls strongly in all gears including 5th now without bogging down. Cool.

Just goes to show that as Taps always says, Henry Ford fitted the parts for a reason - if he could have got away with saving the money on them he would have.....
