Z does not accelerate

Im having a similar problem as everyone. My car will be a terror on the streets in the morning and when first cranked up, then I will hit the gas and the lag is there. I can floor the car from 700 rpm and it takes a moment before it shoots up. The lag is between 700 rpm and 2500. I have an uprev tune on the car and I brought it back to the tuner for this issue. He took out some of the vvel magic that he did and it fixed the problem for a few months. All of a sudden the problem is back. He is sending me another tune and see if that helps. If not I have no idea whats going on. I started wondering if I was running a low compression on a cylinder but I dont think thats the issue. It seems to be a tune issue but now im wondering if its an sensor issue. Im going to keep an eye on this post.
