Also, what kind of compression ratio should be used? 9:1, 10:5.1? Like I said before, some of the jargon has me confused. What does running lean mean?

compression ratio should be either stock or lower.. not 10:5.1 because detenation... even though i know of 2 peeps that have run this type of set up... one was stan and the other guy is 1997nitros (i think that's his name he's got the silver eclipse w/ big FMIC and runs 12's........
as what is running lean? it means you don't have enough fuel to air ratio.. if you run too lean you melt pistons and cause detenation inside the engine...
this below is cause by running lean and too much boost
