Chris`I Posted March 23, 2009 Posted March 23, 2009 The rumour is that not all of them do, but it has to be a very early model. Only real way to find out is to get it dyno'd, fit some mods and have it re-dyno'd at the same place in like a months time. See if it dialled them out. Mine (53 reg UK) did a damn fine job of dialling out my mods at the weekend. Made stock power and a little over stock torque on a DynoDynamics. Still sounds and looks a lot better than the Evo's I was there with Quote
