My wife Jennifer and I purchased a used 04 Envoy. Very happy with the truck. I am glad to find this sight for the info. :thx Have ordered a retune from PCMFORLESS.com by the reveiws on the posts. This will add to our all GM house. A 1985 Chevrolet Scottsdale stepside, 2000 Camaro SS and a 2006 Sierra 2500 Duramax. Is this a forum only or do any members get together for events?
