Its a gsr with skunk 2 mani. I need a vacuum for my wastegate, bov and guage. Which would be the best vacuums and where are they located? I don't have the nipple ok the turbo. All I can think of is the fpr and the nipple in lower back of mani that's free.

Another thing ia my wastegate has two ports. One up top and one low. Which is beat to use?

Anyhelp is appreciated. Feel free to text me 964-328-6166
