Just installed Volant this weekend on 2012 Raptor - couple points:
1) Instructions (or one page diagram) is seriously lacking - and the girl from volant on You tube with demo install on F150 is only a little better.
2) Parts in package - some were not thought out well or I got a bum pack - hood sensor bolt is too long, luckily I had some. Bracket makes plugging in hood sensor difficult, I suggest drilling hole in bracket to thread clip through, and the ford bracket you remove near the front right to put volant bracket under needs to be drilled out for it to go back on as now the spacing is a little to tight.
3) I did not get the cold air snorkel (probably should have) and the additional open hole in front of box make cabin resonance really tough at 1600 - 2000 rpm's. I purchased a rubber 3" plumbing cap with hose clamp to cover hole and it really lowered resonance. I like the earlier post with the ford box put back in place - always an alternative.
Don't get me wrong, I think this is an awesome unit, I just think for the quality of the product they could deliver a little better installation.
