Default STI Utec Stage II map, check out my data log

Is this dangerous? Should I lower the boost on the boost map on stage II?
Only mod on Stage II map was -3 throughout ignition map due to previous knock events on unmodified STIstageIIolf , running 91 octane here in cali .
As you can see UTEC shows no knock but I think anything over 18 psi is kind of high. See how it spikes to 24 psi.

I'm running Invidia catless dp, Blitz Nur spec touring, Apexi short intake, Turbo XS fmic with HKS ssbov, Walbro 255lph fuel pump, and stock injectors.

1) wrong forum
2) post #1 loggers
3) RTFM
4) youre looking at the wrong column. your ign timing is ramping up to 24. your highest boost is 17.8@5291 rpms.

Diddo, looks very similar to my Stage 2 Map in cooler weather. I'm making about 17.2- 17.8 max boost

I just worked on tunning my utec. I can safely run 20psi. My afr were only 9.8-10.4. I was running a mixture of half 93 and half 100. I had zero knocks. My only mods are utec, txs tbe(no cats)and perrin shrt ram. I do alot of data logging to make sure it is not knocking. If you can find some way of getting a higher octane it would be much more safe.

Default re:

Thanks for correcting me. Sorry, still new to this. Is 17.8 psi still high or is it safe for stock internals? Just modified for safer tune for 91 oct here in cali, as directed by Turbo XS tech support. Otherwise how does this data log look? I really don't plan on tuning myself, not until I get a wideband meter and understand all the perameters.
