The Weber DGAS is synchronous opening model (both throttles open simultaneously). This is a high performance alternative to most any DGV (32/36) application. Being synchronous instead of progressive, fuel economy and driveability (responsiveness) is not as good as the Weber DGV series. The common DGAS model is the 38/38.
