I am attempting to disable the pain in the butt VATS system in my 1998 GMC Sierra. Followed the instructions (clicking on "disable" in the VATS column) but it is still "working" (if you call it that) and I had to go through the entire relearn process this morning. I have also double checked to ensure the correct parameter was changed and that is was loaded into the truck. Everything looks ok...am I missing something???
On a side note, I also disabled all my downstream O2 sensors since my cats have been removed. Over the course of a week or so, I would still get a CEL. It has now been 4 or 5 days now with no CELs...I'm stumped.
Last but not least, would someone be willing to look at my stock tune file and perhaps give me some pointers on how it looks or what I could improve on? I have read as many of the stickies I could, but just need a starting point.
Thanks guys!
