I recently purchased a 2015 TRD PRO 4Runner. I've been searching for a tuner option for it with no luck. I see that Bully Dog has them up to 2012. I emailed them probably a month ago to see if they had plans to include newer models. I never received a response. My other 4Runner is a '98, which has a throttle cable. I assume a tuner would modify throttle response and give me some fuel economy and towing options as well. Does anyone know of a tuner to work with the newer models? Does anyone have one on an earlier model that works very well?
