Any ideas why when i rev the sled up my tach appears to go in the opposite direction that it should be? both my dash gauge and my digitron are doing the same thing like the polarity is reversed or something also i went from 500 jets to 440 and still feels like the sled is winding up rather than instant go .. from a 910 crank shop id think that track would be moving pretty quick from the instant i hit the throttle maybe go back to the 370s that i had in when i bought it? that seems a bit lean for 2500 ft and -10c thx for any help
tach running backwards...
