Good instructions, with complete kit. Supplied SCT tuner DOES NOT have proper tune for Avalanche so you have to call and get it. Take the hood off, it will really help installation. Also remove 2 front wheels and splash guards for better access. Install takes 10 hours if you've got experience. Overall great buy, kit was fully complete.
