I just started reading another thread and it seems that I'm not using the correct spring. I have the recommended yellow spring. Here's the link.
As for what I'm seeing. I'm tuned for 9psi and I see up to 10.3 psi on that map. Second map I'm tuned for 10psi and I have seen up to 13psi. It's not a surge or spike because it happens after running closer to redline. Map 3 Is tuned for 12psi. I haven't been able to run this map because I've seen as high as 15psi.
I'm tuned with ecutek. Boost through the ECU. My tuner said the SCG1 BC I had installed wasnt working properly so we switched over to boost through the ECU. It's still plumbed in and I use it as my boost/AFR gauge. As for where its plumbed into. I'm not entirely sure. I tapped the manifold for boost pressure.
BP kit folks. Question on wastegate plumbing.
