I deleted and tuned my 12 2500 last weekend. I did the throttle valve delete as well. After I did all of the upgrades i took it for a test drive. I gave it quarter throttle and the coupler on the throttle valve popped off sending the band out the motor (luckily nobody ran it over). I figured I didn’t tighten the band so I put it back on and tethered the band so if it blew off again it stays under the hood... After that under normal driving conditions it was fine. Then yesterday I gave her the refried beans and pow it popped off. The coupler was slided up as high as I could get it and the band secure but couldn’t handle 30lbs. So I don’t know if I need a new coupler a new band or a longer coupler. Has anyone else had this issue
