If you needed to sell your S4 to save a couple/few hundred a month what would you consider?...

Had a Milltek system on it but it "pooped and farted" a bit too much so he took it off. Did some dynos with their chip in the day we first took my baseline readings. I don't recall exact numbers but I think he got 12+hp extra at the wheels. F1GSD3 are also stock on the R. Great car for the $, but it was hard to go from the S to a highly strung 6 due to the shortage of torque.
