tidbit of humble experience re previous thread on gasoline grades. 

I had switched from premium to 89 type regular, with no observable change in
performance. Happy $avings.  So last week I decided to take the next step
and tried a tankful of 87 octane.  Woe is me!  The car would run, but
couldn't get out of its own way.  Example, going 65 in 4th on highway -
depressing gas pedal just causes more noise.  Shifting into third causes
slowdown!  No high rev power at all.  

BTW, the first thing I did was climb a ramp in second and I got some tasty k
-nocking at 4200 RPM, which is about where the power dropped off when not
pushing it.  Next day, cold engine, barely started, and I bought some octane
boost crap, since I didn't have any toluene on the shelf (gasp!) and things
returned to normal.

just my 2 (I can't find the cents symbol) worth

PS should I bore out my throttle body (or send it to Schaumberg) for
increased fuel economy and more power? (l5 NA injun)
