Thanks for the info Alan, I will try and find out more about that dyno from the operator. I should have removed the solid EGR gasket before making the comparison to be sure. Do you really think that the engine would retard the timing somewhat to compensate?
I ran the car last night, and the air was a bit dense. The car went faster than it ever did ( I think!) but I know that the air outside can make a difference.
What do I need to do to ensure that the egr mod wont subtract power? Get a specific chip burnt with it blocked off?
