i tried lowering it, lowest i could get is 6100
it is mentioned somewhere that there are set values for the maximum RPM and minimum RPM that were put for safety reasons. i also read a post by one of the Miller guys saying that they can change those values for you. so maybe if you really want that happening you should contact them about it.

yea i called them about a few questions i had and they fixed me up. he is working on being able to set those values lower for me and making me a custom tune for it so idk if you have the same ecu as me but if you want it when they get done do you want me to post it here so you can have it???

I really appreciate your offer buddy, but i'm running a different ECU, i'm running the 413 one.
I was trying to help but unfortunately it was more complicated than what i can handle.

i'm glad that the guys at Miller are working on providing what you need, let us know how it works buddy :)

no problem man they havent sent them to me yet its been two days but hopefully they send them to me ill probably call them next week if they dont have them done but quick question for you? i am advancing my timing so i can get more power but i dont wanna advance it too much that i have pinging but do i need to ajust my afr with advancing my timing or should my afr stay the same??? what im trying so say is will the motor go lean if i advance too much???
