02 5.3 553 stage 4 cam
Ok, well I see some big problems and you are not logging near enough data to be helpful.
Your coolant temp is at 250+ degrees, is that accurate or is this thing going to melt down??
You need to fix that issue as soon as possible, the engine will never be happy if it is that hot or think it is that hot.
The log is missing lots of data. Commanded AFR, injector information, cylinder airmass. I see that it's running in open loop but there is no wideband data so you can watch real time air fuel ratio's in the scanner. Knock retard is missing from the logs.
What is the complete mod list?
What is your fuel pressure.
And post your tune file.
Fuel pressure is 55 at railQuote:

I do not know how to add to the log files
I?ve attached the tune
Thank you so much
Also the temp has to be wrong and I know a bad temp sensor is very well my culprit. A temp gun at the sensor showed temp at 200Quote:

This truck also will not have the injector room for the power this camshaft can make. The stock fuel injectors are too small.
Get some new injectors and get a wideband hooked up. That is the only way to tune the fueling to make it run good. Something like this is pretty really hard for a novice to tackle. Not impossible but it'll be a struggle.
Headers and cold air intake I forgot to mention. Stock stall. It does try to pull at stop signs. Also once this thing clears out... it’s making power and runs good till a stop sign or red light only taking off is when it falls on its face back fires some and clears out and runs great. Idles good also. Put it in gear and it tries to die then clear it out and it runs great.
