Went though it all, only thing it can be is a collapsing 12an hose on the pickup. Made that all ridged. So far has kept 70psi but it hasn't left the jackstands yet. I tried forever to get scavenge pressures from tomei so I could confirm this but they didn't seem to know anything technical. The new firmware from AEM lets you shut the engine down at whatever oil pressure you choose for certain rpm so i have it set at 50 for now. If it drops below that something is not right.
