Default HELP Vibration matching engine RPMS

Hey Guys,

I just did poly motor mounts, Trans Mount, UMI torque arm and MGW shifter. Now I have a pretty strong vibration but it seems to be exclusive to the motor. I know people have had similar issues when changing the TA and its usually related to the angle its set at. So that was the first thing I checked. Its pretty darn close to 0 total degrees and if i'm rolling down the highway and put the car in neutral, the vibrations go away. When reving the car in neutral the vibrations are present. They get really strong when engine is under a load up in the RPMS. Noticeable anything above 2k rpms. Kinda freaking me out. makes me not want to get on it. Everything else seems to be running good and making plenty of power so I dont think its missing or anything like that. Do you think this is all because the Poly mounts?

Any advise is welcome. 02 SS M6 60k miles. only other mods are full exhaust and racetronix fuel pump.

Thank you

If it is vibrating idling then probably the poly motor mounts.
