noise/vibration At high speed's or in neutral after running the 1320. and it really only will vibrate after you let out of the gas or if you put it in neutral and cost to slow down from high speeds.

My car has never done this before. Not until last year at the track i launched the car and 2 feet after it broke the torque arm (UMI floor mounted) and sent it up into my floor. well it killed the T/Q arm umi sent a new one to me and the drive shaft didnt look bent but i still had it dyno spun and balanced and new u joints put in as well. the trans is fine and i have a driveline solutions 9 with all the goodie's.

Can anyone shot me there take on this

Mine does the same thing. Started after the 9" install with a vibe coming through the shifter, then, after getting a chassis mount torque arm it comes through the floor now. I have done everything to get rid of it. I also put little rubber spacers between the torque arm/ds loop mount where it bolts to the car, it helps. Good luck

What's your pinion angle like? If it was not set properly with the new torque arm, that could be the source of your vibration.

flywheel/pressure plate damaged? its obviously in the driveline if it changes on acceleration/deceleration.
