how come all i hear people doing black beaer tunes. what you pay isnt worth it to me that same price i can get a programer and a under drive pulley set up. i talk to my neihbor last week n found out he got it done awhile back on his denali. then bought a tahoe and i put in aset of pulley n reset the setting in the ecu. and hes like a little kid driving it around. he 23 mpg on the hwy now.
