i'm looking to swap from awd to 2wd. i think i have about everything figured out. execpt for the service 4wd stuff. i think thats controlled by the bcm correct? or can i just unclick it all in hpt for the pcm? my tahoe has stabilitrack also. i would like for that to still be able to work somewhat for winter driving incase i need it. other wise it will be tuned out for all other seasons.
