when i tuned using my safc, it almost the same fuel added across the board. many people try adding/subtracting fuel at different rpm ranges and seem to have problems with the ecu going back to stock fuel map settings (i call it "limp" mode). I have 680's, safc, 255hp, no FPR and never had a problem with it. Most of the dsm's I have tuned seem to keep the same fuel adjustments from 1k to 7k. The only true way to get it correct is a pocketlogger. good luck -Scott
