I just installed a Banks Power Pack, It came with a cam plate without any number on it. 5 6 ?? I also removed a after market plate at the same time and it also had no number on it. I traced the plate I took out, and faxed it tp TSP they said it looked like a #5. I know Banks wants to stay with the EPA"s compliance. I want the most power. Does anyone out there know the number plate that Banks installs ???
