I don't have any logs to show but just speaking towards what the rep at procharger mentioned to me. Now I was thinking that going to the p1x I could use the same setup and boost but make a little more power with cooler temps. The P1X was designed for vehicles with higher revving limits (newer Mustangs) where the D1SC builds down low just as Saberscar223 mentioned. He just said I would get better results with the d1sc for my vehicle staying under 7krpm with the sweet spot being between 63-6700rpm and possibly make more boost in that range. I was making 10psi at 6800 with a 3.4 pulley on the p1sc1 and now averaging between 12 to 13psi at 6700rpm with the d1sc after swapping to a 3.85 pulley. With that same 3.4 pulley it made 13psi at 6100rpm. I can capture some screenshots from logs if you would like but everything that was mentioned to me was dead on.
