So yesterday I got my very first DSM! It's a 99 GS with a fully built 420a built for boost with a GT2860RS turbo. It was a guy local to me who owned the car and had the car completely built by Beyond Redline in Green Bay, WI. They tuned it on an AEM FIC. My concern is that it has a slight hiccup. I'm assuming that it is part of the tune. When cruising under 2500 RPM or right around there the car runs really rough it almost feels like its cutting out or something. This tune on it is at 14psi and dyno'd about 275 to the wheels for break in. The motor was just recently broken in completely. I am wondering if this is the tune or maybe it's the AEM FIC? I haven't heard the best things about piggy back systems. Any ideas? Help would be GREATLY appreciated
