Superchips, Bullydog GT, or Diablosport Intune I2 for 2015 Tahoe?

I'm going the BBP route with AutoCal. They appear to be the only one that can do the TCM & ECM. The cost is only slightly higher than the Diablew tune that doesn't include the TCM. Plus I'm "close" to a BBP meet location so I might swing by there if the dates work in my schedule. If not, I'll just get the AutoCal unit shipped to me.
