Hey all. Does anyone have a good tune that they use for power increases on a stock 2015 Silverado 5.3? Interested to see what changes you made to gain power. I've seen some great increases on stock trucks with just a tune. Thanks!

did you change the exhaust system atleast, these trucks are corked up big time. unless you do a highflow cat back why bother tuning it?
i would start with the jet 180 tstat , and lock open the muffler flapper door . turn it counter clockwise and run a bolt with fender washers to hold it open. and for the transmission remove the thermostat in the cooler line it overheats those clutch packs after 20 minutes driving hard
The factory 3in exhaust is not a restriction on a factory truck, sure the mufflers aren't the best on the mark for flow but it's not going to be a game changing swapping to a 3.5 exhaust or similar.
The GEN 5 trucks are nothing to laugh at with tuning, it's going to a take a long time to know the in's and out's of tuning those trucks. Doubtful that anyone will just give away a tune to you.
muffler has a warmup valve or backpressure valve that seriously resrtricts airflow, you can probably take it to muffler shop and have them cut it out for a start
here is what I've done to my truck.. not all are performance related
Airraid Jr intake tube with a modified stock Air Box
pacesetter long tube headers no cats and single cutout

can you elaborate more on this sir?
Yes please elaborate more
I don't mind to give some info,.... but I'm not going to just give you a tune I've worked on for hours upon hours I developed???
This forum is to ask questions and learn... that I'll do...
I could not learn anything if a tune was just given to me. I am new to tuning, I really don't have the slightest clue as to where I should start. Like what tabs should I focus
