I asked this in another thread, but since this is more focussed on the egr, I will ask again here. If you set your programmer to disable the EGR, I have read that you still should do the physical plate block. Is this true?
Also, to the OP, 2.5 mpg increase? This seems low compared to other feedback I have read. Do you have a tuner as well?
