Problem with delievered torque

[cmitchell17]

I have never figured out why my deleivered torque is so low. I barely see over 300ft.lbs.

I know with a modded engine without dialing in the maf and VE it will not be accurate, but with a stock 5.3, just exhuast, why would it not read more like 330+ especially with a little added timing.

I can compare my stock tune deleivered torque with my modififed tune and my tune makes about 10-30ft.lbs more torque, but thats at part throttle.
At wot its the its a little more but about the same.

It seems like gm tested these engines under a lot of conditions and monitored the torque they made. So what conditions do I have that I am not making the correct torque.
However, it makes good torque at low rpms according to the deleivered torque. It makes the same torque at 1500-2000rpms as it does at 4000.

Anybody else with a 5.3, what is your delivered torque?

I think i could also control my shift pressures a little better with more torque reading at WOT.

I have cleaned my maf with maf cleaner.

Also while im asking a question what does it mean when your logging TCC mode and it says, TCC apply enabled, or TCC coast? Mine likes locking up when giving it more gas to go up a hill, and then it starts lugging untill you give it more then it finnaly releases. It does this with stock settings too.
