For several years now the common thought has been that a tune on a RC isn't worth much at all but on a QC it's a huge improvement. Well after a some what long and disappointing night at the track I've discovered that a tune in in fact worth a full .4 in the 1/4 mile if you can stick the power to the ground. Just thought I'd share my findings ill start another thread later with track results when I get the video put together.
