I have a set of Depo Z LED tailights and after I hook them up and go to drive down the street anything past half throttle the car feels like it is being restricted. I have called and had them replaced and it still happens. They said they havent heard of this problem happening before. Does anyone have any experience on this or know what could be causing this.

 

Look around for led taillights problems. there are plenty. your taillights use up too much current and the ecu freaks out. some people have been able to fix it using a resistor inline with the taillight, supposedly. either stick to your stockers or get a set from the 06+ 350's if you want to do away with this problem without a lot of hassle. good luck.
