I have the original gauge and I always felt it was a bi suspect. I nstalled an aftermarket VDO gauge in the other cylinder head and it is what I rely on although the oem gauge is in sync with the VDO.Not sure that this would help but I did read a post about checking the gauge with a 3 volt battery to insure it is reading properly but right now I don’t remember where it is. I believe it was posted by @doug7740 …I read way too much and now it’s gotten a bit confusing
