    5.3 cam/80lb injectors/ turbo Need help getting idle set

    So I just got my VCM suite in the mail and had to give it a go. I got a base map from JSRacing products who had a similar setup injectors etc. The motor will start up and then sputter erratically then die. I adjusted the FA vs Coolant temp vs map, leaned it out about 10% but after scanning it realized I made changes to low in the KPA table to affect anything. So figured I would see if anyone sees any obvious issues. I am thinking it may be really rich due to elevation differences and the cold weather. I'm going to set up my wideband tomorrow hopefully. Tune should be 3bar OLSD with IAT.

    I am going to try and verify tomorrow, but that was one of the reasons I got the base tune I did was that stuff was set up already...
