Does this look like I am doing it correct? I s advises to adj inj slope down by 3%. See attachment. Thanks for the help...

log looks good... you logged the wrong throttle parameter tho...

you wanted to log the Commanded Throttle Position for your newer truck/predator... not the absolute throttle...

Ok, I will change the throttle issue. How do I get the attachments to you to make the custom Tune?

Dude you are running extremely lean. the air fuel ratio should be around 12.5 to 13.3 when you hit the gas i jumped up to 16. 14.75 is where all the gas and air burn perfectly. you will see more power running a little bit richer. Im guessing around 5-7RWHP. I have a 07 Silverado 5.3L with around 400RWHP.

hahaha!!

did you look at the whole log??? he's not lean... he wasn't going WOT... max throttle was 67%... not even into WOT/PE mode....

he had let off the gas from a steady cruise, and his rpms dropped to 574-584... for 1-2 seconds.. hundredths of a second... and the afr bumped up... as soon as he gets back on the gas pedal, AFR is normal... all is normal operation... no issues here....

and no worries... he's gotten a custom tune since then anyway...
