Like the title says, I get a boost spike when the TCC locks at WOT. I have boost set at 23psi and it jumps to 29-30 when the TCC locks. Within a couple seconds I start to get a little knock even though AFR is steady. Just too much boost for the timing. My setup is below, however I am running a Mease DP with a Turbonetics Racegate and a manual boost controller plumbed like in the pic below. What can I try to fix this? I have never ported the wastegate hole on the turbo, do I start there? Do I try a lighter spring? Maybe loosen the tention on the spring?
