Well normally I agree. However these are just some old rims and and I am sure overtightening isn't causing the vibration. I will torque the TT rims when I put them on and cross my fingers!

Overtightening wheels can warp the rotors though, so even if the wheels are shit, its still important not to overtighten.
if it only happens ~60mph or higher, it's not loose lugs. you'd notice that at 5mph.
its got be out of balance , how old are the tires? i have had a lot of tires when they get mileage start to vibrate at speed, warped rotors is a old wives tale
"warped rotors" is bullcrap. they might be heat-treated due to excessive braking; but that would only produce vibration during stops--not at speed.
Rotors can be warped by overtightening the wheels. That is fact. The warped rotor by excessive braking is the wives tale.
And my comment about overtightening is a seperate comment from his vibration issue. I just noted its bad.
I don't know how old the tires are. The tread is awesome on all four. However, as I mentioned earlier I have a hound from every town! They are all the same size and I checked to see if any weights had popped off and all is good. I hate the R/T wheels! My wife wants me to hold off on putting new tires on my R/T TT wheels until spring. So, I guess I will just have them balanced to make sure.
It only vibrates at 60+mph...so my guess is the wheels/tires out of balance or a broken belt.
Make sure to change the caps in the working TCU if they are original or it won't be a working TCU for long.
Unlike the ECUs, when the 47uf cap by the voltage regulator pass transistor leaks there is a very good chance the regulator will fail and dump 12v on the 5v buss to all the chips blowing them.
^is the the genius whose advice i've been warned about?
No, the Steve you've been warned about is Steve68.
