Benefit'* I know of without scanning after installation:
#1: No more loapy idle.
#2: High rpms under load feel a lot smoother -engine revs under load almost as smooth as the Series II L67 in my brothers 97 SSEi.
#3: Even though I've been battling fouled plugs, a chopped # plug wire, and detonation (I need to work on my fuel system now), it pulls harder and smoother than ever before.
#4: 5 minutes after turning the engine off after some hard driving I can grab the manifolds with my bare hands and the feel hot after about 3-4 seconds -couldn't go near the stock one'* for almost an hour without getting burnt before.
