I don't know much about the Volkwagon GTI other than they are light (2900lbs)...my son and I pulled up while one was revving his engine at another truck...the GTI had already started through the intersection when we rolled up next to him..from a roll we blew his doors off...at the next intersection we went from a dead stop. I am pretty sure if the GTI dude races another diesel he will definitely roll his driver side window up cuz we dumped a load of smoke in his face not to mention that we dusted him from a dead stop...that was courtesty of McRat's tow tune
