Tune trouble shooting / questions

Trying to figure out the rough power level of the tune that is currently loaded in my truck,

It’s 27 degrees inj timing at 3100 rpms
130mm3 fuel rate at WOT
29000 psi fuel rail pressure at WOT
29 psi boost at 6000 foot elevation

Thanks in advanced, trying to trouble shoot things and have been told I am on the stock tune and others have said I am in the race tune. Even when iv loaded the stock tune

Call your tuner with your VIN. If it's motor ops like your signature says, they'll know what's on there
