This is my first log on my stock 5.3 What to do next lol i'm new to efi live

 

Are you running E85?

 

Nooo why?

 

Why you running it in open loop? Why are you commanding 9.xx air to fuel at WOT? Who tuned this truck?

 

The guy who tuned this truck was the guy who did my transmission.

He said he used HP tuners to Correct my speedometer and raise my shift points, but i think he played around with some things

 

Dude, this tune is all kinds of jacked up.. Your commanding 12s AFR at cruise speeds where as most tuned and stock vehicles command 14.3-14.6 AFR. Your timing is horrible also. Hows the truck run lol?

 

Don't tell me that lol! The truck honestly runs fine haha i have no idea how but it does, it beat my brothers tuned duramax. Should i try and find a stock 5.3 tune and go from there or should i fix this one? Keep in mind im new

 

From the data you have logged anything would be better. Yes, download a stock 5.3 tune and flash it in. Should run much better.. If your gonna learn tuning you need to get a wideband also

 

Okay yeah i'm planning on getting a wideband soon, Where can i find a stock tune? Tune File Depot ?

 

Yep that will work!
