So guys just picked up my car and i have to say the power is great, but i have a small problem if its a problem. The car is fine at idle normal chop, but once i hit the highway and go above 60 mph the car starts to vibrate hard, i don't know if this is normal since i never added a cam to a car before. Also i did the conversion from l99 to ls3 and added 3.91 gears.
update: Got the car fixed it was the driveshaft like "Litle88" said and once they fixed it car was running better. Also the 3.91 gears makes a big difference just saying.
Thanks guys,
