We're back with Real Street Performance and their 2020 MKV Toyota Supra. This time they've done a few tweaks to the ECU tune and added a downpipe, needless to say the results were very positive! They were able to run what we believe to be the quickest 1/4 ET to date for any 2020 Supra and we also tested it against another stock MKV supra. Stay tuned for more 2020 MKV Supra coverage!
