The problem being that the car being discussed was tuned in such a way that the gearbox was set up that when you shift to the next gear, you end up below its powerband and the car lost time in the part where the RPM had to increase back into the powerband. Sorta like when you tune a turbo that you keep shifting into an rpm range where the turbo can't build up the needed presure, you need to make sure your gearbox allows you to stay within the powerband when shifting.

On a side note, this is exactly the problem I have with my ford station turbo diesel, I need to pull it beyond its powerband before shifting or it will end up on to low rpm in the next gear and the turbo lag on this thing is idiotic, its power band is somewhere between 2000 rpm and 3200rpm, but if I shift at 3200 rpm, I end up around 1500rpm. If I pull through to about 4000 rpm (near redline) and I shift I get back into the power band but the power between 3200 and 4000 is not to good, better then 1500-2000 rpm thoughSmile.
This reminds me of Episode 4 of Fourth Stage and I know all about the turbolag of your ford. Wink
