How many degrees of timing are most of you running with a 8-12# supercharged 4V on 91-93 octane fuel. I am getting my final tune on Saturday and wanted to know where the "safe" zone is. I think my last tune had like 19 or 20 degrees.

18 degrees of timing with 16psi on 93 octane pump gas (daily driven car).

I think most tuners like to keep it around 18/19 degrees on a street car.

I was running 12-13 degrees total timing, using 91 octane with about 15psi of intercooled boost (Upgraded Impeller S-Trim).

Sadly, 91 is as good as it gets for pump gas here in Cali...
