87 Octane parameters vs stock 5.3L 6-speed

[jayman9782]

Does anyone know the difference in parameters between the stock/factory settings vs an 87 Octane tune on a 5.3L 6-speed? I have a 2017 Silverado. I installed the canned ECM tune and also changed the TCM tune to firm.
Thanks.

there are lots of changes, too many to list, timing, fueling, limiters, torque management, shift pressures, etc...all are optimized for improved performance.

Thanks for the response. I installed it last night and did not feel or notice any difference. I’m hoping that changes.
