I just had to have all the afm lifters replaced and I was now going to look into a tune from you guys. Its a bone stock Yukon 5.3 FFV. I was wanting to turn off the afm and see about a mpg tune. Right now we are getting 13-15 mpg mostly highway. I don't know if that is because the afm wasn't acting correct or what, but I didn't know if a tune would get better results and will it affect our towing or anything. We will start towing a small 6x8ish trailer and looking to upgrade to a 6x12 enclosed later this year or next.
Thank you,
