Stock unopenned motor (low VE). I had to slow spool down to keep from getting compressor surge. I am going to save the TA62 for a 4.1L motor, and run it at lower boost.
Running the TA62, I compared recorded boost vs rpm and compared this with the compressor map, and yes I was in the area on the map showing surge.
I know others have done a lot with the 60-1 compressor, but I just do not have the experience.
