what he said

"From 1-2 was pretty minor. Your long term fuel trim numbers were running pretty consistently rich so I leaned out the chip 12% and should have fixed that issue. Chip 3 I richened the accelerator pump programming 15% to compensate for that 12% that I took out of all the fuel when you tap that throttle and should have correct that problem to where should have given you all the benefits of chip 1 but with better fuel economy."
