LT1 Editing
havent used lt1 edit in a few years but if i remember correctly there is 2 timing tables, ones for 0-4000 rpm other for 4000+
those tables should be labled rpm, and manfold air pressure(map KPA)
map is basicly vacume but backwards, higher number the less vacume. so 100 kps is no vacume
most cars will run at wide open throttle between 95-100 kpa, depending on how restrictive everything is.
what i would do is just take out 2 degree from 80-100 kpa range. you will want to do this to both table.
