However, just wanted to run this by you. Mine feels like it pulls a bit better just after a gear change. I was told its because the built up air isnt being vented to atmosphere so the intercooler, charges pipes etc stay pressurized so you dont have the lag of the turbo filling them up again. Or is it just a placebo effect of being told that?
