People are making good power with the VF52 on pump, along the same lines (in some cases better) as the 1.5xtr on pump. Which the OP graphs also re-affirms. With that being said, the 1.5xtr will excel with higher octane gas.

If I was concerned about spool and running the car on pump. I would have went with a different turbo.

False. The 2.5xtr will make more mid to top power than the 1.5xtr, both on pump and on better gas. True on the 1.5 spooling quicker.
