The Atomic has earned a reputation as being one of the most reliable and effective manual boost controllers on the market, boasting a repeatable and steady boost curve, quick rise rate, and great bang-for-buck!

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 dyno graph shows the Atomic boost curve in green, and the factory curve in blue. 4th gear is used for both tests, and proof that the Atomic was set to the same peak level is seen towards the end of the chart as the two curves meet. However, notice the massive gains down low in the rev range, as much as 18kW (23.4hp) 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 1700RPM earlier in the rev range. All this WITHOUT exceeding the factory peak boost level, and for a pocket-money price!
