Apologies for quoting SussGQ Mate but is there any possible air restrictions when it’s at its peak, 3rd 2,000k - 2,800rpm I find old faithful OEM’s love to breath best maybe?

i wouldn’t think so, it’s 4” piping from snorkel all the way to turbo with a massive ryco filter and the cooler pipes are all 3”. it’s running 20psi so i suppose there’s a chance it could be sucking a silicone join together, although the boost doesn’t drop to 0 when it happens, just a couple of psi
