You "gearheads" reading this thread, please help. I'm very interested in how the Active Fuel Management is working out, specifically on the 5.3L W-bodies. My local dealer is offering me an excellent deal on his last Monte Carlo SS...but I'm not sure. I was a victim of the V-8-6-4 Caddy deal back in '81 (yeah I'm old). I understand technology has come a long way etc. etc. Can the AFM be deactivated? Bypassed? Chip replacement available? Or does it work so well I need not be bothered? Any and all comments and suggestions appreciated.
