My C4 S4 has an MTM 1+ chip. (Supposedly) the original instructions said to
turn down the wastegate perch 6 turns. I recently did that and the turbo
hits a little harder, a little faster (it de-emphasizes some of the on/off
effect of the boost map). It might hold boost a little longer too.
My 200q20v now has an MTM Stage II (thanks Jim P.!) Should I be doing
anything with the wastegate?
