....Like I said.....and this is ME...i use a combination of two re-learn procedures.....here are both...
Transmission Reset / Relearn
The 5R110 automatic transmission on the 2008 – 2010 6.4L Powerstroke has what is called Adaptive Memory and is constantly learning and adapting to different horsepower levels, temperatures, driving habits, etc. After completing the Install Download process on the 6.4L Powerstroke, the Transmission Adaptive Memory is automatically reset. We highly recommend performing a Transmission Relearn procedure after installing H&S tuning to help the transmission perform correctly with the added horsepower. The 5R110 automatic transmission will eventually learn over time on its own, but the relearn procedure gives a good baseline for the adaptive learning and helps to speed up the learning process. To perform the relearn procedure, please follow these instructions:
When re-training the transmission, ALWAYS follow posted speed limits. Do NOT attempt runs in adverse weather conditions such as snow, ice, rain, wind, or any other conditions that may affect your vehicles traction or impair your visibility!
1.After H&S tuning is installed, perform each of the following 0-80 MPH runs while in the HOT power level. During this relearn process, you may experience hesitation during shifts, hard shifts, or defuel patterns, all of which are normal:
•0-80 MPH @ 25% throttle position, then slow down and come to a complete stop.
•0-80 MPH @ 50% throttle position, then slow down and come to a complete stop.
•0-80 MPH @ 100% throttle position, then slow down and come to a complete stop.
The Transmission Relearn procedure is complete.
Note: On any vehicle using 3” or larger lift blocks under the rear leaf pack, it is HIGHLY RECOMMENDED to install traction bars. With any added horsepower, failure to do so may result in harsh shifting and may cause premature transmission and/or driveline damage.
The following is the Spartan re-learn procedures>>>
>SPARTAN TCM
1. From a stop, accelerate the vehicle to 55-60 mph at approximately 1/4 throttle. DO THIS TWICE.
2. From a stop, accelerate the vehicle to 65-70 mph at approximately 1/2 throttle. DO THIS TWICE.
3. From a stop, accelerate the vehicle to 70 mph at approximately 3/4 throttle. DO THIS TWICE.
4. From a 40 mph roll, press the accelerator to the floorboard quickly (forcing the truck to downshift) and accelerate to around 75 mph.
5. From a stop, acclerate to 75 mph at wide open throttle (press the accelator to the floor immediately). DO THIS 2-3 TIMES.

Regarding LBF>>>>>from H&S Site as well....
Low Boost Fueling
This option allows for adjustment of the amount of fuel injected under low boost conditions. There are 5 different settings for Low Boost Fueling:
0 – Lowest Fueling
1 – Low Fueling
2 – Medium Fueling (Default)
3 – Moderate Fueling
4 – High Fueling
Note: The low boost fueling adjustment will affect ALL power levels. This option can only be adjusted during the Install Download process.
