Fuel tuning...

[Marc Piccioni]

If you are having trouble getting the plugs to colour on street gas the you 
might want to try draining the tank and put say 5 gal's. of VP 100 unleaded 
in it. Then make your hard runs.

Not have to be new.  Pull a couple easy ones and see where your at.  If
evenly bone white, as compared to pure white, ya prolly can use those. 
 Time
ain't as important as load.  So 15 secs
in high gear, better than 15 secs from a stand still.  This is a street
machine, so you don't have to be as good as a NASCAR team.  Quick braking 
to
idle/stop, fine.  If the plug has a different
color then when you started you getting some reading.
  Using new plugs with the current fuels are/can be really hard to read,
sometimes ya gotta put some miles on em for a good base for things to stick
to.
