Can I Fix This Toyota GR?!? - Tuning Session PT.1

MIJ have swapped cars with me to see what I can do to boost their Toyota GR, but on the DYNO it's nothing but misfiring! Can I find out what's wrong with it and FIX it before they want to swap back? Always have a great time working on other people's cars, and despite the issues with this one, I still had a blast! All measured on the Maha DYNO.
