The gauge failure posts cursed my car

I bought the RT-engineering IVR their claim is that it mimics the OEM mechanical even in the wave form. So we will see.
I'm sure you'll never see a 1v difference, but it's still not quite right. LOL I've used ona before and it worked well, but I have a glass jar full of the 6v ones and heat sinks. I caught on sale "somewhere" a while back. lol
