just new to this site i have lifted my fj with a 3in. skyjacker lift kit and then added a set of 33in. nitto terragrappler tires since doing so i have noticed my speedo is not always correct, on the highway from mile marker to mile marker im a 10th of a mile off. the other day i was driving thru town an came up on a speed billboard and it says im doing 35 mph and checking my speedo it also says im doing 35mph . what gives, i also hear that due to the larger tires that my anti lock brakes are no longer working and the shift pattern on my automatic transmission is also effected. so i guess my question is , does any body know of a company that has a recalibration module that will work on the fj to correct these issues / JOE
