Help! Prosport boost sensor leak.
Hello, so I have tapped the vaccum line from the BPV and run it to the inline air-filter and then to the boost sensor. The problem is, I apparently have a small boost leak there. I've tried both 5/32" vac tubing from advance auto parts and the tubing that came with the gauge. I've zip tied all the connections but it still leaks.
I've tried to adjust the connections a couple times, each time after I fiddle with it the boost leak goes away and then it comes back after the car sits for a while.
Does anyone have any suggestions on the hose spec, the air filter, T-junction, or anything else I should be using? Please let me know, thank you.
I've also had the suggestion that this is the bpv opening early, is that a possibility?
I'm working with Eric Minehart - he believes there's a leak since my boost values and the engine load are higher than they should be given the tune. After fiddling with the tubing they go back down to the expected values.
Specifically, I'll hit 20.5+ psi manifold relative pressure with 3.6 g/rev engine load where the numbers should be around 19.5 and 3.1 nominally.
