I was on my way to my fathers retirement ceremoney and right before I got onto the highway to get there, my car went from getting into boost, to just bogging down completely!! No more turbo spool up or anything! Only code I have thrown is P0113 and went to the dealer for repairs. Told me it was the IAT (Intake Air Temp) Sensor. It has been replaced and the car still runs like it's eating mud for breakfast. It can barely accellerate. Can anyone tell me what is going on? I just got a few mods done but I'm about 99.999999% sure you don't need a retune after installing a bigger intercooler?
