    2014 5.3 Engine tune

    I'm new to tuning but doing my best to catch up by reading/watching youtubers test and tune. With that being said I've been tuning the trans on my truck for a while and it fits my driving style just right. My truck previously had a TCM and ECM tune on it when I bought it. Had a dealer put a new transmission in it a couple months back and I'm pretty sure they wiped both of them and loaded factory back to them.

    I've got the TCM back like I want it but I am curious if anyone has a factory tune I can look at to see if the ECM has been wiped or not. I want to know what im starting with, the engine side of tuning is definitely going to be struggle for me so trying to make sure I start off right. I will also be forever grateful if someone would throw a tune up here as a base that I could go off of to get started with mine.

    Your engine tune has been modified quite a bit. The DOD has been disabled. PE tables have been changed significantly. Timing tables have been changed as well. You might consider increasing the rev limiter a couple hundred rpm. Your 1-2 and 2-3 shift points are a bit higher than your rev limiter.

    Thanks for the reply, are you meaning for WOT or partial? I haven't played with the WOT side as much because the truck is on 36's and WOT doesn't transform her into a race car or anything Hahaha, ill check it out and mess with them some more.

    As far as the engine side goes do you think its improvable? it runs like a champ and has good power but if there is room to make it better then i might try to dig into it. Definitely going to pull your tune up and look at the stuff you've pointed out. Thanks for that file!
