OK, I did the mod on LJ's website and it helped a little, but not much, its still pretty split, like around 108/160 at idle, cell 16. My LTFT in other cells I noticed are in the low teens to around 109. I measured my fuel pressure with a new Sunpro gauge, and it said 48 with vacuum, and 54 with (yeah, I know thats too high, but my old Autometer told me different). Now its set at 38 with vacuum, and 44 without, which is closer to what most guys run. This should bring the LTFT in the other cells closer to 128. I will have to check out my air check valves to see if one went bad, or maybe block off my EGR to see if thats possibly leaking. A few guys have also told me that this is just an inheret problem with LT1's and big cams, like Buttercup said. My pulsewiths for the injectors at idle are like double from one side to the next. OK, back to the garage, I will post more info soon.....
