i just got the smarty and added it to my truck. i already have the edge juice with attitude hot. When i run the 0-60 times i run best with the smarty on 8 and the edge on 5. then i tried the smarty on 8 and the edge on 3 then 4 seems to run even better but didn't do a test. has anyone else noticed this. also my main concern is that i cannot run the smarty with the edge on stage 6, seems to surge really bad and has low power. i tried it with the smarty on stages 4 6 and 8. can someone tell me why this is and if it is normal. any information would be extremely helpful. thanks
