Can't figure it out. It started this winter. After initial start when I would come to the stop sign at the bottom of the street the truck would drop rpm and stall. Once it had 10 minutes to warm up, while driving, it would be OK. Now it stalls all the time at a stop after starting fine. I am beginning to think I need to sell my Hypertech and buy LS1Edit to fix it. Any suggestions?


5.3, MAS, 80mm TB, FIPK, Gibson ST, HT PP

 

First give hypertech a call and tell them what's going on. It might be something simple that can easily be fixed.

 

Removed the hypertech program and see if it still does?

 

Goods points. I will remove programming tomorrow and see if it happens on the way home. If it fixes it I will reload and try again then call HT if it continues. Will post findings.

 

I pulled the HT programming and the truck still stalls. Now what?!
