I have a friend at work that had a super charger that he took off his Chevy Avalanche he told me that if I want it I can have it. I am thinking of using it he has the hole kit. But the tuner he has is for his truck we both have 03 but I have a Tahoe both have 5.3L second I have 150k on my truck. What dose every one think. To much for the old girl and his old tuner might be all I will have to invest in. Any ideas will be welcomed.
