I have some of the usual bolt ons and would like to tune my car now for a little extra power, but I plan on getting new wheels sometime and a KB sc. If I wanted to change my tire size after installing the KB, would I have to get KB to retune or get someone who specializes in tuning KB to reflash my program. What kind of system does KB use for their tuning. Do they use something like superchips, where I could buy the flasher and do it myself?
