Have not been to the Power Vision web pape for ages and they now have a short video on how to use the basic autotune feature. Plenty of people have been asking questions on the forum about it, just have a look see.

I read here in the forums to auto tune from the original tune, not one that comes from Powervision.

Can any others confirm that one?

 Where in Sydney can you buy the Powervision?

I had a locked tune and made copy of that tune with power vision and then auto tuned from there worked a treat managed to remove some of the lower down chugging that was there after the custom tune was done dont get me wrong had great tune from tuner but used auto tune to smooth it out down low worked a treat with the wide band kit installed
