What you are wanting to do is a tune. Anytime you disable or change things in a vehicle computer, you are tuning it. If you are going to tune it, you might as well tune it right. Do some research and find a good custom tune person. They will know exactly what to do and there will be a night and day difference. I have one on my Chevy Tahoe and it has 196,000 miles on it. Better gas mileage and all around drives better. I can tell a difference when I drive one that is not tuned and one that is.
