Yep my S4. My GLI was totaled so rolled the dice on this 2016 S4. 80k miles. Had a pretty solid CARFAX so feel good about it. At 60k previous owner went APR Stg 2(93) dual pulley, Ultracharger, APR cooler and TCU tune. Goes fast ;). Always had an AP so no map switching sucks. I have E85...
Glad you found a local tuner! Odd that Stratified wouldn't tune for E as I had 2010 GTI with K04 Stratified tuned for E30. I did have their aux fueling kit though. That may be the difference.
Great looking car that has lead me to a question. I'm new to Delaware and have a Mk 6 GTI w/K04, Cobb catted down pipe and running aux fuel. I need to run smog. I know your car is smog exempt currently but how did you plan to pass smog with your current mods?
