best tubing to use for vacumn/boost lines?

l`ve been tweaking things on my turbo system and l`m not happy with the combination of tubings l`ve used to plumb my wastegate,blow-off valve and FMU,etc. l found that motorcycle fuel line looks good and seems to be resistant to expansion so l have tried that. The best thing l think l`ve found is Japanese car rubber vacumn line with the colored braiding on the outside. l`ve had to scrounge this from the autowrecker and to do it right l need more of it. l guess l`m concerned about heat and what it does to the signals with silicon lines so l don`t use any silicon. My latest purchase is what appears to be PVC tubing and if l can secure/seal the ends l think it won`t expand at all. Anyone have any input on all this? what`s everyone else using? line expansion may be something not worth worrying about..
