Who says they're closer to 140bhp? :} :} Ford's accurate engine bench dyno says it's close to 130bhp - I know which I'll believe
It's all the same in terms of percentage improvement though eg.
130 real vs. 140 according to the rolling road.
Then 160 after the bluefin tested on the same rolling road. Therefore still only 20bhp or so increase which isn't great.
But how about the Bromley's tunit report. The mondeo started out at 147 according to the dyno but only achieved 167 at the end. You could read this two ways.
1. It only had 130 at the start and only really achieved 157 at the end.
2. It really did achieve 167hp.
The team at Bromley's did comment that the actually gains were lower than expected due to high output of the original car.

This could indicate that there is a max achieveable power output through adjustment of standard setup. Therefore if you already have a fast one then you won't get as much increase.
Now I know this has been raked over many times and each group of followers (Ford, VW etc) think their cars are more powerfull than claimed but some cars do get quicker as they get a few miles on them. Also not all engine are equal, you get good ones and bad ones (mines a peach

) so isn't it possible that there is a natural spread of 10 hp either side of 130hp and it's just the luck of the draw which you get.
Take MPG for example - I seem to get 47 to 48mpg but some other TDCi owners are fighting to get low 40's. It seems to indicate that there is some difference between indenticle engines.
