So I see lots of stuff about heat soak causing significant turbo lag in hot weather. Does anyone know around what ambient temperature major heat soak starts to kick in? I'm trying to figure out whether I should just live with it in the summers in Dallas or fix it some other way.

 

i don't have a turbo car so I really don't know. but unless you are looking to race the thing everywhere you go, I would just deal with it. or get a FMIC.

 

Yes FMIC is rellly the only way to fix being heatsoaked.
Otherwise , live with it during the day , till it cools down at night
