Hey everyone HeWhoAngersYou here, posting a link to my video of a 2013 WRX starting stock then adding a K&N drop in and a Mikey Botti Pro Tune, no other mods period. Dyno video and video of this WRX on the 1/8 mile track. Incredible gains and NOTHING negative to say about the tune. Car drives awesome has not changed the drivability of the car at all. A/F perfect and no detonation as hard as you can hit it. Dyno being used here is a Mustang Dyno (called the heartbreaker) Mustang Dynos are known for being the truth machines of the industry. Mikey sure knows how to tune a Subie. check out this video of the Dyno and Track time. Leave comments on the video and be sure to Share, Like and Subscribe to my channel. Thanks for watching. https://www.youtube.com/watch?v=9t3UtroPU_U
