What codes need to be deleted when doing the Vacuum mod on a 4l60e? The kit i have has the resistor to install which im guessing is to trick the computer.. but wasnt sure. Either way, what codes need to be deleted or what else needs to be changed? Thanks in advance!

Its been a few yrs since I did mine but don't bother with the resistor-just go in and turn off the codes associated with the PCS. I cant remember how many there were (2 or 3 Im thinking)
I assume you are doing this mod because you are boosted? If so, dont forget to install the little check valve thingy to vent off some of the pressure under boost or you will damage the vac modulator.
