No chips, this is not a mass produced chevy, a Eurocharged tune is all and the best there is. And and new mods like Cai they send a new retune for free
Search forum and there is a new ground control kit available now.
I have 2 of the cats removed, but in il we do not have smog checks.
The kenwood 558bt is a great head unit that matches perfect also.
