| Why are you making 18psi with it off? Do you have special WG springs to have that base boost? My base boost is 12-13psi. I run: 12-13 on the street with 91 octane, which is rare (ECU program 1) 18 on the street with 100 octane (ECU program 1) 15 at the track with 100 octane (ECU program 1) 23 on the dyno or drag strip with C16 (ECU program 2) Given that you have access to 93 octane, you could probably tune for 16psi on it and still be safe in most conditions.
