    I don’t know much about car computers but I just put the cxracing turbo kit in my Lexus IS300 (2jz-ge) and now I need help tuning it. Can I just tow or drive it to a dyno tuning place and they tune it up and it’s all good or do I have to buy a new ecu, chip, piggyback or something. Sorry if it...

    I want to boost my IS and have seen a bunch of people running the stock ecu. I'm not willing to take the risk I'm too worried about leaning out, and the car will overall be a lot better with a stand alone or piggy back. I don't want to break the bank but I will if I have to. Anyways what is the...
