hmm, I never knew these values were changed. You are right Grandpa Kim, this makes little sense.
I will raise the values in the next Version of DNM. Not sure about default, though. It seems the intention of the original authors to make retrofit cheaper. So I am likely to follow the spirit of the mod and offer a discount for retrofits as well.
Speaking of retrofits, how about raising the 'Retrofit Max Percent Difference in Cost'?
