David, where you running 109? i thought you had pump gas in...
the different octane won't make a difference in the injectors themselves. You weren't tuned to 109, so it really won't make the car different, except it won't pull timing as much because it would resist detonation better.
unless the car is that reactive, which i doubt, it would run off its previous curves and reactions for 91. maybe if you ran a tank or 2 or 109, it might start adapting to that level of octane. but i doubt it.

what is so wrong about him putting 109 in it? he didnt put leaded in, he put a higher octane fuel in to take advantage of it via some tuning. there is nothing retarded about that. if you have a problem with him racing his car or modifying it and taking it in for warranty work (which may actually be warranted in this case, cant say for sure) then you need to take your car back to the dealer. GM didnt sell a turbo car with amazing suspension among other things for people to drive to the grocery store. its meant to be beat on, and the owners should be covered to an extent.

not at all, the mods he has would not cause the issue that probably is at the root cause. Intercooler piping and higher octane fuel don't cause over-rev. A missed shift does. until we know what's wrong with the car, you can't possibly blame any of the modifications to his car.

the ONLY thing i could see you having an issue with is if you put in leaded. i do not know how the DI would matter with that, but i have run leaded race fuel through mine several times. generally will just shorten O2 sensor life (obviously dont run it with a cat though)

109 is acually better burns slower hense more stable airfuel ratios and usly lower airfuel ratios it prevents detentaion and keeps cylinder temps lower i run 109 everytime i go to the track just for a little extra assurance i wont get pre igniton i think u prolly floated ur valves and possible droped a couple what sound does it make when u crank it over

And isn't the NLS only for 1-2 and 2-3 shifts? And...I've never been to the track, but from what I have observed, shouldn't you not be shifting into 4th anyway?

The fuel did not blow it up that is for sure. 109 octane has a much higher flash point so no detonation.
