Okay, I'm super confused! Please look at frame 920 on, notice how it's defueling and cutting back at 40% tp? I can't figure out why? I feel like I've tried everything.

How did your truck turn out?

Still defueling on shifts, I put the stock tables in and added 10%. I don't understand because I'm not asking for a lot of fuel or pulse width down low. How does the tune look on 5?

The customer needed his truck for work so I can't play with it until this weekend again.

Did you get a chance to log with the pid list that I sent you?

One thing that I see is the fuel pulse ramps up with to big of gaps. Try to keep then close to 200-250us as your going toward the top end. A little blending is needed.

On hot tune I raise the base torque close to max. I don't feel that 10% is not enough. just keep it stock in the starting and idle area.

I'll look at it tonight also.

Do what it takes to hit setpoints with as little adjustment as possible.

Look at your base torque tables and torque limiting injection tables. The smoother the better.

Okay, I'll give it a shot.

Not necessarily. Stock is the best... Just up enough to hit set points on the big end.

If you messed around with the Throttle Based Injection Quantity then Torque Limited Injection Quantity and Base Torque will need to be massaged.

Stock tables are fine for a small tune, but they usually defuel too much on the big tunes and get a bad layover on the shifts at part and mid throttle %.

Log the tune and you will figure it out, but like Kory said, go back to stock on those tables if you have messed around with them and make little changes until you get it.

Good Luck
