I'd suggest a couple things... first, a JDM MAP sensor. This will allow precise boost logging, as well as give you the option to use mrfred's true EBC (ie., you dial in a boost level and the JDM MAP reports back to ECU)

Using pump gas only, 26psi is pushing it... I was able to spike 26-27psi on pump with no knock, but honestly I'd rather not run more than 25psi on stock internals with only pump gas.

I didn't said that the car lives with 100 octane, always. No more than 1-2 knocks. AFR little rich for now, but I'm working on boost.

The load goes to 285-290 for 0.2 seconds in the logs (3300 rpm), than 260 tapering to 210 at 7500. Can this be safe? I see logs with 245 load at redline with stock turbo and internals...
