I just wanted to see if anyone else that has a good running car with proper ignition timing has the same experience with the slight glowing turbine housing. Of course I know it glows while under load but mine was cooled down and idling for 10-15 minutes after a very easy run.
I cannot time anymore initial advance at idle without going too advanced under boost with my stock ignition system.
It would be ok to test more idle advance but really be of no value because I cannot run it there anyway.
Anyone take time to notice there turbo at night?
