Been a while fellas. Just got my IS38+ installed. Switched to the is38 adjustable map. Initial settings are 21psi and 93 octane. I'm on stock fueling. Going to do some datalogging, but wondering if I need to start at 21psi and work up from there, or if it's ok to start higher like 23 or 25? I feel like I read/heard somewhere you can do 25 on stock fueling? I just don't want to start too high, I'm not Snoop.
