I did a full AFM DOD delete on our 2014 Escalade. Retained the VVT by using an OEM L92 camshaft. Plugged that relief valve in the oil pan. Installed a Melling 10296 oil pump with the +10 psi spring. Hot idle in drive, 600 RPM is 30 PSI, cruising at 60 MPH and above it holds 58 PSI. Cold start up at 32 degree's..... 68 PSI. Runs like new. It also has an oil bypass filter that takes up about 2 PSI....
