I don't dispute that, but on the over run it's a different story.
Some ECU's don't allow it, i've never mapped a car on cossy management but i'm sure if it's as good as people say it will be able to not smoke between gears.
Chip, yes i've done this before the other day at brunters i went "off the map" so i had to richen the top row, however this created a rich spot between the last grid and the desired boost level, it flicked to a 10.6afr but didn't black smoke.
