It seems just yesterday we were celebrating the first 9-second 2015 STI. Now, not even a year later, JrTuned has done it again! This past weekend, the 2015 STI 1/4 Mile record was re-set by Junior and the guys at Prime Motoring. This is a car that utilizes the factory ECU with an Accessport V3 running COBB Speed Density tuning strategy. It idles at 950rpm and drives like stock. Hard to believe you can hop in a 1000+ WHP STI and drive it to the grocery store if you wanted!
Support for this feat comes from some of the top vendors and tuning shops around the country.
