REFLECTOR: Running LOP

Sat Dec 16 06:38:41 CST 2006

Andy,

How do you tune the injectors?.....take them to Air Flow Performance in
Spartanburg, SC.  They do the same thing as GAMI but at half the cost
and twice the service. (even though the question wasn't directed at me)

Steve,

Can you elaborate on how you are tuning your injectors?
