ok ive been reading this post and i had the same problem almost. after installing my vig 2800 i threw up an ses light. missfire code. caused by the torque converter having to much slippage. this was corrected with edit and now everything is fine. no ses light.
allthough my truck never went into limp mode. but i do have a built tranny. so maybe that had something to do with it.

 

Hmmm...so I guess any torque converter will cause this, not just anything above 3000.
What code did you throw Thunder and how did you correct it with Edit?

How hard was it to learn Edit? Did you just go by trial and error?

 

been getting allen from nelson performance to fix it and then comparing files im still learning.

 

TM? That **** is ALL gone from my tranny...

 

Misfire probably due to the small diameter confusin the computer... small diameter = less rotational mass.

 

oh.... well that sounds a little more reassuring flyer.... about what percentage should be taken out?.... 80.. 90...?

 

All if you have the transgo kit that came with a video.

 

Under "Transmission Diagnostics"
"Test Parameters"
What is your "Torque Converter slip" Normal slip and fail RPM set at?

 

TTT. Can you tell me what these numbers are set at 01Thunder?
