Hey Steve, I am having a problem with the recent torque converter i installed. I have a 2009 gmc sierra 5.3 l 6l80e with a cheatr v.3 cam 219/230 .607 .604 117lsa and a circle d multi disk 2800 stall. I am having problems with the engine stalling when put into gear first thing in the morning. It idles fine in park and neutral but once its thown into gear it stalls out the engine. I can get it moving after the 3rd or 4th start up but holding the break and feathering the gas. Once the engine is hot and trans fluid heats up there is no issues at all. I let the trans get to about 70 before i even try moving the truck. I have been trying to fix this problem with my EFI live tuner via Auto cal with no such luck. Once i get this thing moving it seems to run great and the problem goes away until it sits for exdended period of time. I have attached the file my tunner sent me for the trans. I cant seem to upload my EFI logs for you to see. Any suggestion would be appriciated. Thanks Ryan

I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.
