Over the past week or so during the Texas heat I have been noticing boost fluctuations near red line. I mainly contributed this to the heat (95-99 during the day). Yesterday I opened the hood to examine some of the vacuum connections and discovered that the Vortech provided lines were very mushy almost to the point of collapse. After discovering this I headed to the auto parts store and purchased fuel grade lines with the same inner diameter (much thicker). I replaced all the Vortech supplied lines leading to all devices. After completing the replacement my boost seems Much more stable during the heat. Has anyone else experienced this problem besides me?

Are you talking about the vacuum lines that go from the one point on the plenum to the SS box and to the FMU and BOV? if so, i should take a look at mine too, but i havent noticed anything yet?

I am - they are in my opinion very poor quality and made a difference in performance once replaced. "Just my opinion"

Interesting comment. As usual, you make a valuable contribution.

If you are interested, here are some high performance vacuum hoses. These are really good hoses and perform really well under heat, almost nuke proof
