Might have had a brain fart
This post has made me realize a point i overlooked when deciding to go with the Mass- Flow system. With the Edel Pro- flow system i currently own i have the ability to set parameters such as fuel and timing how i like at any RPM with the hand held programer an important aspect for what i'm trying to do. I'm getting rid of the Pro Flow because the electronics do not allow it to run properly at under 10" of vacum, i won't be able to make it idle. In order to update my Pro- Flow it would require new electronics $ 1800.00,new intake Vortec to standard 23 degree $350.00 and larger injectors $440.00. Fortunately i won't get hurt by this as i still have the ability to choose between the new Edel Pro-Flow & Mass-Flow if the Mass-Flow does'nt have the tuning options of the Pro-Flow.
