It's quite similar with GM. Every winter when we get cold we see vehicle after vehicle with the small gas turbocharged engines all lined up because they are in reduced power mode because the intercooler froze. We install updated heated pcv kits, winter fronts, ecm calibrations to keep the tcc lockup off when cold..
