Best Shift points for 5.3 (Tuned).

[Roddy8]

Hey guys what is the best shift RPM on the 5.3? I'm running the 4L80 with 3.73's. Factory it appeared to shift around 5200rpm and with my diablo tune its shifting around 5400rpm. I am getting a custom tune from Diablew in a few weeks but I am curious where I should set my shift points. And I am curious what other tuners, like Black Bear set it at? I have heard 5700-5800 is good?

 

Truck is mostly stock, except for tune and Airaid Intake.

 

Thanks

Your tuner should know

Stock it should shift at 5600. Something seems fishy here it should shift higher than that
