I am working on a 1999 6.0 with iron heads has a 224/234/580 lift with 114 sep cam and headers. I disabled all the dtc's and my comanded is not even close to my actual. I did a full flash of a 2002 camaro tune witch was not the same os with a manual to see if it would be any diferant it still did the same thing. i have done a lot of work with the fast xfi just not as much with efi live but have never had this much trouble with one before. I can double my ve table and it wont hardly change my afr. I know that what i am doing is not right but trying to get it to respond.The motor has stock injectors i can get it to make a pull but only with the comanded down around 5 to one and the just makes no sence and when i say its lean i mean like 16 or more to1.this is a pull with the camaro cal in it.
