Just 3?
High idle, 65 Tow, 100 Perf.
The 140 is going to smoke a lot and anything else will just be a wasted position. If you find that you need more than 3 tunes, you can always send the chip back for a reburn. The nice thing about stage 1 injectors in an older PSD is that you can run them without a chip and they will work just stockers.
