we did back in the day on our 335i intercooler. Less pressure drop than stock (similar stock design on those cars).

After tuning a bunch of these, I have noticed that our intercoolers will cause an overboost condition when running the same tune before and after the intercooler. The Fiesta ST ecu chooses WGDC based on calculated Compressor outlet pressure (aka pre intercooler pressure) based on a table on the stock intercooler. Basically, when only the intercooler is changed, MORE pressure gets to the throttle with the same amount of turbo WGDC, meaning less pressure drop with this FMIC. Hey it better, the flow area and the end tanks should flow ALOT better, less pressure drop.
Maybe one day ill break out the DAQ1000 and put sensors in both charge pipes, but too much going on right now.
