Can I use Data Master To find out if I'm Running lean. I'm not fimilar with this program. The Problem Is my headers are starting to glow after new 383 t trim install. It has 42# injectors with 44psi of fuel, so i would figure that it's getting enough fuel. I see that another guy is having the same problem in the LT1 tech area after a heads/cam install. I've been told that its running lean, timing retarded to to much, or running rich and burnning in the headers. Any info or suggestions would be great.


Thanks GS355
