I would say 15-18 psi to start out on the safe side BUT this is all dependant on how your AFC is tuned. Since you bought the car with all those mods you really need to learn how to use the AFC before you really go screwing with the boost. Because you have a 1G I would also learn how to watch your knock count as well. If you can achieve 18psi on 93 octane with no knock then I would say your off to a good start. I'm not a 1G person so if any of you 1G tuners want to chime in feel free.

yeah if you have access to 93 octane no more then 18 IMO..
