Default Problem with dbw throttle body on vvti swapped car

Hey guys, I recently picked up a vvti GTE swapped IS and for the most part it's amazing. Unfortunately it's got some nagging issues and the most bothersome is the throttle sticking around 2100 rpms. This results in bucking from the clutch when decelerating in gear and when the clutch pedal is pushed, throttle stuck at 2100. Only way to get out is with a rapid throttle blip/rev or putting load on the engine and bogging it a bit. I got a replacement TB and installed it, however that one seems to best messed up as well, car starts at WOT, and butterfly is open at rest. What are my options here? Should I just attempt a bypass mod? Or can the dbw unit be fixed?
