So in short, not very.

I believe you can choose in the settings whether or not the dials show obd ecu speed or GPS speed and can compare them. But in general torque is not accurate it tends to overestimate things like the virtual dyno feature is a horrible attempt
Also important note a K&N filter would no way yield a .8 second improvement if we're assuming a perfect environment and conditions (launch, tire temp etc) A maximum you'd get is 5 HP according to some dyno tests. I don't think that's near enough to shed .8 of second off an AT.
