Another test to try to break 300whp on the stock turbo!

This was done on David Jackson's 2014 Ford Focus ST.

Cobb Accessport with JST Performance custom tune, Steeda FMIC, Levels Catless DP, maxed out oem wastegate actuator, E30,ect, ect..

The car put down 297whp on its first pull from the E-tune i did on the car a few months ago, and also made an impressive 285whp on 93 octane. 302WHP with no special tricks ( no upgraded wga or balance shaft delete like our personal car).

So with some fine tuning, the right parts, and a good tune. 300whp is now definitely doable!

Correction factor was .981 on this run FYI
