I was just wondering if anyone here has used a 2" rpm gauge and has had a problem with shifting efficiency due to the small size of the gauge.

Thanks in advance for any help

 

My Autometer tach is 2 5/8", which isn't much bigger than 2". Can't say I notice a problem at all, plus it's a little bit more stealthy looking than a 5" monster tach, (not saying that's what you would get ).

 

Exactly why I want the smaller one
