UD Pulley Electrical issues Please Help
I have a LS2 with a 25% UD Pulley. I put the engine in my infiniti G35 and put the pulley in during the intial swap. Problem I'm having is I'm having bad voltage drop at high RPMS and Pcm wont let me over 6500RPM. I've read that a UD pulley can cause this issue at high RPM. Has anyone ran into this problem or have any ideas why Im cutting off at 6500? 2G wires ran to alt and starter only and 2G running to both PCMs.3 Ground 2G straight to the block and two to the body. Any help would be great.

Its the only thing left. Belt isn't slipping. I dont have a alt. that has a changeable pulley. I'm going to put my stock pulley back on and see what happens. Remember I am powering two PCM in this car. Infiniti and E40. I have three ground directly from bat. two pos ran 2 gauge. Wiring is correct. Just when tuning the tuner say voltage starts to drop at 6K and motor wont rev anymore at 6500. Pulley is the only thing left. The car runs perfect and has no issues at all beside robbing me of a little bit more power.
