The Atomic Boost Controller was tested on an MY02 Subaru WRX (whose only mods were a turbo-back exhaust) back-to-back with the factory controller. A base-line power run was performed with the factory boost control, and the boost level was measured at the same time. The Atomic was then installed and set to the same peak boost level of 0.9bar (13.2 psi) so that the spool-up time could be accurately compared before and after the installation. The Atomic logged massive gains down low in the rev range, as much as 18kW (23.4 hp) at the wheels! This increase in power shows that the Atomic allows the boost to rise significantly earlier than the factory controller, which on the road represents much better acceleration from a whopping 1,700 rpm earlier in the rev range. All this without exceeding the factory peak boost level, and for a pocket-money price! It's important to note that the MY01-02 (MY02-03 in the US, GDA chassis) model responds very well to this modification, because the factory boost mapping is very conservative in an attempt to keep the torque curve flat and the power delivery linear (which totally kills the feeling that you are driving a turbo!). Note of course that boost can be increased above the factory level for more power gains, but the purpose of this experiment was only to show the improved spool-up potential on this particular model WRX. So, if you want your GDA WRX to REALLY feel lively, fit an Atomic or Reactor boost controller for the best "bang-for-your-buck" modification you can make!
