I have no experience tuning a 12v other than this truck. I put a 160gov spring into the afc and had to trim a coil to get it to full fuel at about 58psi of boost. Down low the spring doesn't have tension till about 10psi so this is noticeable on the street. I have to accelerate slow to avoid pissing other drivers off. And when this acceleration I can barely pull out in front of traffic in time when turning onto a busy road. I drive slow normally too and I still find it difficult to keep smoke low. Also I stay out of o.d. Unless I'm going 55+ on the highway because it's smokier in o.d. I may try an aftermarket afc spring that has tension down low because now I essentially have no afc below 10psi.
