So I just bought my IS300 and am looking to get this turbo kit. I e searched the forums (maybe not good enough) but had a question about engine management. If I purchase this bolt on kit, is it required to get an engine management system? If so, any recommendations on the most user friendly one to use? I’m not looking to make any ridiculous HP gains at this point. Just want to add a little more kick! Thanks and sorry if I missed a thread with this info in it.
