My speedo is off by 5 mph and the rpm's seem to be about 300 to high, Can anyone tell if this car has a gear in it or if my shits just jacked up. Thanks in advance. Its an auto btw.

I couldnt tell you if it has gears in it but I changed my gears from 3.6 to 4.1 and it made the speed off about 10 miles per hour and raised the rpms. It is at 2500 rpms when about 55 mph

at 55 i think im puttin along at about 1900-2000. Pretty sure thats way over what it should be. But then again maybe my shits jacked up. My tuner says im doing more like 1600-1700 at 55. But i cant help but to wonder.
