2011 Stage I J-fonz tuned S-Tronic (DSG) B8 S4 versus Stage 3 K04 B5 S4 and BMW 335xi with JB4 and bolt ons
Some good runs here showing off the strength of a tuned B8 S4. The 3.0 TFSI supercharged V6 motor responds very well to a tune showing tremendous gains tune only thanks to an increase in boost pressure. The S4 camera car you see in the video also has the S-Tronic dual clutch gearbox. The B8 is pitted against a Stage 3 K04 B5 S4 although it is a tiptronic (automatic) which is slower than the manual cars. The 335xi features a JB4 tune and bolt ons.
The B8 makes easy work of the B5 which is impressive. K04 B5 S4's have run 11's @ 120 miles per hour but those are manual cars. The tips are simply slower and it shows.
The B8 S4 versus 335 race is interesting as the S4 puts up a very good fight considering it just has a tune and the 335 has a JB4 tune along with an exhaust, intake, and intercooler.
The 3.0 TFSI continues to impress, video below.
