Ok, I’ve been driving my car for 2 weeks now, got a good feel for the car - everything if fine, but I don’t floor her all the time. Just noticed few days ago, sometimes – there is no turbo, feels just like normally aspirated car… Why?

Here is was I was able to narrow down so far:

*First start in the morning – fine, 30 min driving to work/school
*Start after work (sits all day 8-16 hours) – fine
*If I stop at gas station, shut her off – restart = no turbo for 10-15 min thereafter…
*Driving very slow in traffic (stop and go) for 15-20 min = no turbo for 10-15 min thereafter…

Almose seems like heat has something to do with it? Any one experienced this? Thoughts? No check engine light…

Thanks,
D
