Its a little different when you get into mods as its all relative. The 4cyl mustang in the video had drag radials as well as a tune. You put drag radials on a stock 5.0 and your running mid 12's and that's without a tune. They are still pretty quick for the money though.FWIW tune on Ecoboost 'Stangs can actually go just as fast, if not faster than the 5.0..... Tune only has bee in the mid-high 12s. These are potent little engines.
