iNSTALLED AFTERMARKET GAUGES, BUT THEY ARE READING WRONG, NEED CALIBRATED SOMETHING.
FOR INSTANCE WHEN i AM DRIVING 30 IT SAYS 90. SOMETHING I FORGOT TO DO, SOMETHING i DID WRONG, OR EASY FIX?

 

perhaps you are in kilometers?

 

when i installed mine the directions said to reinstall the needles when the car was running and at temp, so you might want to take it all apart pull the needles off and start the car, then re-install the speedo needle. is that the only one that is off? if the others are off i don't know how to help ya on that, my direction said before takeing the needles off to start car bring to temp, and mark needles on someting so that you can put them back in the same place as they came off. I would at least try it for the speedo it might help or fix the problem. good luck

 

It says youre name is Bullet, im guessing you have one. If so, they should sweep themselves and calibrate.
