For interest I have put this graph together comparing the power and torque for my Patrol previously and currently.
The blue lines was a dyno test done in August 2010.
The green line was a dyno test done in December 2010 when things start to go wrong, before the Weber modification.
The red line is a dyno test done on Friday afternoon "as is" with no tuning. The ambient temp. where the test was done was 45deg C, I dont think this is ideal to get a true reflection of the power available, as the Patrol is much more responsive and where I used to gear back on inclines from home to work I can now stay in 5th gear. I think there is some room for improvement with a good tune-up but are more than happy with the performance as is.
