the 19me is what you are running.

 

should i get the 23

 

i got the 22 on mine. i dont think the 23 will help the heat when you are on the higher catcher numbers. i think the later numbers where made to help the overhead messages on certain trucks.

 

ic what is the power on demand i messed with it once and my truck went to half power or less i dunno what it was doing but it had no power what so ever but i will probably do the up date tomorrow and see if it helps anything

 

remember to put it to stock before you update it

 

ok i didn't know that thanks
