So my last rom tune was tuned for a sr20det t25/t28 setup, 550cc, z32, factory compression. Since a 2871.64 is not that much bigger will the tune still be efficient and safe?
From what I understand the the ecu is a load base type, hence you can run 16psi on a sr t28, so I was wondering if a 2871.64 would run the same around the same boost pressure. I'm thinking of also retarding the timing by 5 degrees.
