intake and exhaust tune for 17 sierra 5.3

[Crimson_Sierra17]

ive got a 2017 gmc Sierra with Volant CAI and Gibson 3-1/2" catback.
added 4 degree in the first rpm range then 3 in the second and 2 in the 3rd also added 2% fuel acroos the board.
increased fan power and throttle sesitivitey, turned off 4cly mode and raised shift points 100rpms.
truck feels good not much of a diffrence seeing its on 35s.
how much timing and fuel would yall add on 91 octane

[mikel]

None.
You really shouldn't add timing for no reason, and the tunes are already set up to run max safe timing on the recommended fuel, so, chances are you are just knocking like crazy and making less power than stock due to the added timing.
I would suggest setting that all back to 0.
Also no good reason to add fuel unless you have a wideband that says its running lean.
We spend a lot of time developing these tunes, so its rare that making arbitrary adjustments will show any improvements over what we've provided on a stock application.


Thanks
