I am fairly new to tuning, have successfully tuned about 10-12 vehicles , but have never ran into the issue I am having now. It is a 6.2 engine out of a Cadillac Escalade, the ECM is for 2008 GMC Sierra truck, LS3 intake with LS3 MAF, MAP sensor, and injectors. Mild cam. Can you help me with what you do would do with the spark table? In the scan file I see the spark drops way down low to like 6-8* when the issue is happening. What could be pulling timing down to that low? Again, any help is greatly appreciated!
