I met up with JimE one day who had an Insight EGR on the bench. I have been meaing to modify it so the valve is always open and take a spin around the block to see how it impacts.
I imagine with a honda hybrid it would help regardless as mo throttle would equal mo assist with the Insight design. Kind of the reverse of a prius which would go from electric to gas, but Ive been fooled before by modern technology
I can say the newer insight is much more drivable with it blocked off and I lost 3 mpg doing so.
