I think odds are pretty high that the wholed IP unit is non-turo. Is there any easy way to determine if it is turbo or non-turbo? The IP unit has what looks like a metal ID tag on the left side. It is hard for me to read the numbers. Because of the angle of the unit i used a mirror. The numbers are small and my old eyes could not read them. Hard enough to read with their image being reversed let alone reversed and small.

All response and comment are appreciated. Thanks in advance.
