This Audi A6 C6 3.0 TDI was used to compare two intercoolers: Mishimoto and F-MIC. An earlier dyno run with the standard software recorded 222 hp and 450 Nm; after ECU calibration, the same setup had reached 283 hp and 571 Nm. The test focused on intercooler performance, not simply peak power.

With the standard ECU software, both intercoolers produced similar results and logged air temperatures; approximately 38°C was reported at maximum engine speed. When the car was tested with the calibrated software, a pipe on the smaller F-MIC intercooler came off twice under high load. The Mishimoto intercooler held pressure during those test runs.

These findings apply to this Audi and the specific component sizes tested. The presenter concluded that the F-MIC model used was not suitable for this 3.0-litre engine at the tested load; this is not a universal comparison of every intercooler from either brand.
