I really need some advice on this. I have an on3 single kit on my car, and a genuine Tial wastegate instead of theirs. My car on map 2 will creep almost up to target (17psi) and then almost go into a safety and go immediately back down to wastegate psi ~12psi. I’ve ran logs and sent to Terry and it’s not a lean issue. I’ve checked my connections and I’ve ruled out leaks. I will attach the log when I get back to my pc, but I’m really stuck here. If I run on map 1, then it holds boost on the spring perfectly fine. I’m pretty much convinced that it is an electrical issue of some sort either tune related or Mac related

Which tune are you running? I was getting something similar when trying to run it off the JB4 with single firmware. As soon as I added a BEF all the problems disappeared.
