id suggest that you fellas get yourselves a Air Density Gague, there a several brands out there (google it),, "Longacre" is the one i use,, makes tuning so much easier, but, remember to keep notes,,
also, while ya at it, get a Spark Plug Reader (little magnifieing glass/tourch) brmotorsports.com make a good cheap one,, allows you to get a good look at the plug and read whats going on in there,,
with these two gadgets you can get a "real" handle where the tuning for a particular motor is at,,
Target EGT's,,, Gasoline - 1550*
Alcohol - 1300*
Nitro - 1700*, but you dont want to go there,,
