Recommended Shift Points for 2013 Silverado 1500 4x4 LT with the 5.3 and 6 Speed Auto transmission

Question:

I have just installed a Superchips Flashpaq F5 Performance Tuner on my truck. I also have gibson headers gp129s, Bosch iridium spark plugs, Taylor 409 10.4 mm wires, AEM cold air intake 21-8030dc, 1 airaid throttle body spacer 200-616, flowmaster super series muffler3inch single in and dual 2.5inch out. I want to change my shift points to maximize efficiency of getting the power to the ground and so its a little quicker and was wondering what recommendations/advice yall have. Thank you

The one I recommend is the Superchips Flashpaq F5 Performance Tuner # SU2845 and is the correct model for your 2013 Chevy Silverado 5.3 liter truck.

I contacted our technical representative at Superchips about the modifications you have made on your 2013 Chevy Silverado and what shift points they recommend. In the instructions about the downloading function to adjust transmission shift points it states that not all features marked in the chart are guaranteed to work due to unforeseen differences in OEM vehicles. I included the instruction link for you as well.

With all of your additions there may be some things you are limited to. Many times an aftermarket cold air intakes may give different oxygen readings.
