I have a 2005 ext cab 4x4 short bed ,duramax /allison with a MBRP cat back .I want more power but I don't want to kill the trans .I a'm trying to figure if the Edge EZ or the preditor would work better I want as trouble free a system as I can get .It would be nice to go more than 95mph but not at the expence or smooth reliable power .also is one better at getting rid of the dead spot on take off than the other ?

My vote would be Predator. I have both and love them, but the Predator seems more responsive down low. Diagnostics very handy also.
