ok this is a stupid question, but i was wonderin about these reverse gauges and the current gauges i have go to 130, and the white ones go to 140, can they work still? or what do i have to do to get it to read right?

 

either they extended the speedomoter to read 140 (which doesn't matter b/c your speedo is way inaccurate after about 85 mph anyways) or they messed up and made the guages wrong and put 140 where 130 should go...if it's the latter, then i wouldn't use them for the sake of innacuracy...

 

why is it so inacurate after 85?
