I have been unable to enable the EGR on my car, and from searching around it seems that HP Tuners removed that item from the newer software versions, is there a way to get the older version of the software to make the change? Or is someone here able to help me out and make the change for me? I guess i could always rewire it to the AC pressure input but the PCM is buried under my dash and i would like to avoid that if possible. Current tune file is attached.
