2015 Silverado 5.3L ltft question

[09silvy]

Been years since I have used a diablosport tuner. Looking to put the diablo tune on my 2015 Silvy. After installing the tune is it still necessary to go in and log/adjust fueling for ltfts so they are in 0 to -2 range? Just curious if the newer vehicles still require it. Thanks!

It's not like the old trucks... You can't adjust the injector slope on that newer truck, since it's direct-injection... You'd have to get a custom tune done so that the MAF sensor table could be adjusted in order to dial-in the airflow/fueling... Which I could definitely get you hooked up with, along with a lot of other settings I adjust, smooth-out the shifting, adjust shift points, etc etc...

I've done thousands of these trucks over the years and do them weekly...
