Default strong vibrations at low rpms after clutch/flywheel install

yesterday i got my car back after having an ACT HD clutch and ACT streetlite flywheel installed. forewarning- i will be calling the shop later on today, just seeing if anyone has any idea, or has had this problem before.

the problem is- when i am in 1-4th gear at about ~1600rpms and am giving the car more than 30% throttle, there is a violent vibration. the vibration goes away after ~1750rpms, and everything seems fine after that. this is a pain when going around corners, or pulling away from stop signs since i am usually in 2nd and pulling from low rpms. the sound of the vibration gets amplified since it resonates through the whole dashboard and sounds really bad. yesterday i was driving with the wife, and she gave a disgusted look over to me and said "they broke your car" haha.

anyone have any ideas?

Engine/pitch mount broken or not fastened down?

What type of disk?

As suggested check the mounts for the engine and pitchstop. also check the tranny subframe and mounts. Might also want to try rotating the driveshaft 90* and see if that helps.
