Thats not true. Dom 1.5 is has same compressor wheel as Dom 2.5 at 71mm, only difference is turbine wheel is 56.5mm on the Dom 1.5 and 60mm on the Dom 2.5. Difference between two should be spool. Both turbos shouldnt have problem making over 400whp as they are essentially a GT30 turbo with custom billet wheel. Now trick to this turbo is higher boost as that is where it will start to shine, and of course higher octane fuel whether its E85, race gas, or meth.

Also all of my virtual dynos generally have the same shape as my dyno pulls that I have done, this was with my stock VF39 as I havent dynoed my Dom 1.5 that I have. But was making 380whp VD at 21 psi and ~365whp on airboy on the Dom 1.5 with 10cm EWG. But unfortuanity this was with broke ringlanding as I thought source of my oil smoke was turbo so I replaced my VF with Dom, later I learned it really is internal.
