You'll have to go through the tune in the fueling and idle areas. I forget exactly which table was skewed and can't seem to find it. What I found was a table that was supposed to be all 0's in the 2D graph but when you looked at the graph it showed all zero's but there was a spike in the graph. Still read zreo but was a spike. When looking at the numbers in the table all read 0.0 untill you hit the +00 button up top a few times. There it was, 0.0049 for example. Changed that to all zero's and all was well. I'm pretty sure it was a fueling multiplier table.
