Like my tune was setup to get to roughly 18 psi, but the boost would go up and down from like 14-18 psi through a pull, you can't feel it, but can see it in a graph. This is going to fix that and give me, and once it's released, others, consistent boost control. I think the problem is worst for those using flashpro, but all users suffer from it to an extent.
