X3M needs about 3 seconds to build rpm and boost since the DME limits the rpm to 2600 max. DME is targeting 10.5psi for the launch. The Magazines that test the X3M that do not allow it (don't understand) to "boost up" will get slower ET's. I was guilty of that as well on the M Day test. With 2 people in their X3M I launched it like my M5 and probably left on 5psi of boost. Plus 4000FT DA plus my bad launch still netted a 3.9 second 0-60mph....this thing will move out if launched properly!!! I'm hoping for a 3.6

Thanks for sharing your results. 3.6s seems realistic based on everything shared to date (IND's dyno and 1/4 mile and your weight and numbers).
