hey speeking of the low gear planaterys will these set a code when used? randy at hughes is checking for me.says he never sold a set for the 4l80e.anyone actually used these?i also found a small shop that has a set of 3.06 planaterys for the 4l80e but he says he has never installed them in a late model only in a stand alone system.

 

why would they set a code? I am sure you can tune for them if it does.
