Not hurt at all...and yes I see that. Nice response to me in your posting of the dyno chart.
bumping back into topic
My thoughts on having the timing advance, one of the very first bolt on mods for me was the custom built short ram intake (which sounded great as well as it gives you a few more horse power) the gains are typically in the middle to higher end of the RPM scale, and one looses a bit of torque on the lower RPM scale. The timing advance helps to restore some of the lower end torque lose and again helps to give you a few more horses through the middle and higher end RPM's. You would be correct in having to run 91 octane or run the chance of retarding the advance back down, I can think of no disadvantages to having the timing advance done with your current setup of just the SRI. I also was able to note some improvement in the gas mileage as well after havng the advance done.
With that said, wouldnt advancing the timing be pointless if it flucuated so much based on driver input, and ocatnce choice...
Im very confused on this. I thought that on our cars once you set the timing it doesn't reset automatically. I know 4th gens do not stick like ours. But if ours supposidly does stick, then how can it retard itself once it recognizes lower than 91 octane?

how about this straight up question with no research.
will my timing advance I just got retard itself if I use 89 octane
As long as my understanding is correct, yes it will retard itself until it detects nicer gas that doesn't detonate under the advanced settings. No, it is not a permanent retardation (Chrome says that's a word!). The ECU constantly adjusts the timing to prevent bad, bad knocking. Just watch the timing value jump around on an OBD-II tool! It skips and hops and bounces to keep everything gravy.
The dynos prove that the timing advance affects both partial- and full-throttle timing curves, as it adds +2/+3 to the base number, if you were confused on that.

Thanks for the reply, as long as its not a permanent retardation that makes more sense and as long as it keeps +2 degrees to the base number (aka initial or @ idol) than thats great and thats what I thought it would do. i understand it is constantly working/fluctuating to maintain safe detonation per driver input/octane etc.
some interesting stuff I found in my current

I did the advance timing at the dealer (to 17) 1 week ago and I have some pinging now......My car never saw a drop of fuel less than 93 octane (almost always Shell)...I didn't notice so much added power .........
