I have a 79 stepside with a 01 LM7/4l60E. i am in the nazi state of california and i am trying to get my vehicle so it will pass smog. I keep reading that i can make all the tests pass in the tune so that i can actually disable and mock up the egr and secondary air stuff. is this true i cant find a whole lot of cali stuff and would like to find out all of the options and create a write up for cali swaps. Thanks!!
