The whole of TVR 400 cat map is richer than Land
Rover's 3.9 1994 cat map and also the TVR 400 cat map is slightly richer on
full load and slightly leaner on light cruise than Land Rover's original
1992 cat map. factory Chimmaera 400 cat map is the
idle set to 950rpm

LR's 3.9 non cat
map(2) and TVR's 400 non cat map(2) are the same.
