In today was a T5.1 180 bi turbo DSG van. This is using supermarket fuel. The initial dyno run it made 177 bhp and 400nm of torque but once tuned (including the DSG gearbox on this van) it made 198 bhp and 415 nm on one run and then 194 bhp and 428nm of torque. These never make huge gains but they certainly drive a lot differently after tuning.
