reliable

Hello, Im thinking about installing a Dynatek Fusion module. I want to advance my timing 4 degrees. Other than running premium fuel is there anything else I need to do for a reliable build? Im not trying to shorten the life of my FZ. Anybody heard of this module? Thoughts?:

I have a iPhone 6. I'd like the ability to have it in view for map use but I'm not sure I want something permanent bulky and ugly. Sleek and removable would be best but it has to be reliable, i don't want to see my phone drop and skid along the road because the mount was crap. :) Any...
