Does anyone publish a horsepower number for a Silverado 1500 tune?
Some do. Of 12 Silverado 1500 tunes in our catalog, 3 publish a horsepower figure and 9 do not. Every figure below is labeled with where it came from: an independent test, the manufacturer's own claim, or an estimate from comparable hardware.
the ones that do
why the rest don't
MPVI4 is a flash/logging interface, not a calibration - actual power depends on the tune loaded. Neither hptuners.com's MPVI4 page nor the Livernois listing makes a horsepower/torque claim of its own.
This is an ECM unlock/upgrade service (mail-in $299.99, or a pre-unlocked replacement ECM $699.99) that enables the stock ECM to accept aftermarket calibrations - makes no horsepower/torque claim of its own, confirmed directly on HP Tuners' own page.
NONE PUBLISHED for this specific 2019-2022 GM 1500 kit - description only uses general language ("Get power you can feel," "Disable DFM for full-time V8 operation") with no numeric figure. Older DiabloSport pages for the pre-2019 K2XX-generation Trinity 2 do publish numbers, but that is a different SKU/platform, not reused here.
NONE PUBLISHED for this 2019-2022 GM kit - page states the i3 platform generally "increases horsepower & torque" but gives no quantified figure for this SKU.
