im not quite sure how to explain it but when im anywhere from 40 and below just cruising, my truck just jumps like 400 rpms up and then back down and will keep doing it until i speed up or let off the gas. Any suggestions? I would post a video but i dont have a camera.

 

converter locking and unlocking? I have the same problem around that speed, i just run in 3rd if im stuck in traffic going that speed for awhile, the converter locks in 3rd and stays locked better. Then when i get out of traffic, just throw it back into OD

 

You probably still have the stock lockup settings. I can post up a screen shot of my apply and release tables if you use EFI Live.

 

i had i tuned with efi live but i dont have the software. in the process of trying to get efi live. i dont know anyone around here that has tuning software.

 

hey randomhero can you post up a screen shot..? ill get colton (charcold-bowtie) to look at it. hopefully im getting my truck tuned for nitrous this weekend.
