Hello all, I am looking into tuning a S5, I don't have access to the car right now. But I am wanting to go over what hptuners has to offer in tunability before mentioning to my friend that we may need to go a different route. If anyone would have a stock file from a 08-12 S5 4.2, or something similar. Would be much appreciated. FWIW it's just going to have a full exhaust, possibly a intake for now.
Thanks
