I know some have swapped the gear on the cable and most just deal with it being off. But thinking about the electric clusters adding the right resistor(s) should put it back in line and knowing the % of increase in tire size should tell you what resistor to put in.
Whats the thoughts around this?

 

I bought one of these a few years ago. http://www.summitracing.com/parts/jet-50110
But i resold a while back and never installed it to know how or if it works

 

Thats basically all these boxes do are increase or decrease resistance. It may take me a little while to get everything together but i will try out a trimmer pot like the tach has.
