I had the Ford Performance ProCal put on my 2015 Ecoboost, and the Mishimoto clone intercooler. Two questions: 1) I notice there is a rubber type flap that partly hangs over the intercooler. What is it? Wouldn't it reduce the effectiveness of the intercooler? 2) On acceleration, and then letting off the gas, sometimes I hear a popping, or clunking, sound -- not loud. I just recently had new tires put on the car (thank you Pirelli), so I don't know if it has something to do with the mods, or putting the tires on the car.
Any ideas? Thanks!
