Bought this for my 2011 Avalanche. The concerns in previous reviews regarding battery drain and throwing codes were on first versions, those issues are corrected now. The biggest decision is whether to spend the extra $$ for a tuner. I am extremely happy with the purchase and it is well worth the money!
