there's also east coast customs and toshi
toshi is a little different though, he tunes it on the road, meaning you drive around while he sits in the passenger seat and tells you what to do for most of the day. he's tuned 150+ rb engines and many other engines. prior to him doing tuning he also used to do some spirited street driving in japan.
