ST225 Power Tests Revealed.

ST225 power tests revealed: five remaps, back to back, in Performance Ford Magazine.

The October 2012 edition of Performance Ford Magazine compared five high-level remaps for the modified Focus ST225. Pumaspeed supplied a simple Ultimate Edition tuning box with two tunes: the Stage 3 (310bhp) and the Stage 4 (for the larger Focus RS Mk2 412 or 440cc injector set).

The test car, owned by one of the magazine’s reporters, was fitted with a 3-inch downpipe, 200-cell sports cat, cat-back exhaust, Pro Alloy ST/RS intercooler and a CAIS. The graphs below are taken from the article and show back-to-back results for: Pumaspeed Ultimate 310 (red, Stage 3 equivalent), Pumaspeed Ultimate 412 (pink, Stage 4 equivalent), REVO Stage 2 (light green), JWR Autotech Stage 3 (blue) and Superchips Bluefin Stage 3 (dark green).

Power: five remaps back to back

Stage 3 Ultimate 310 and 322

Our Stage 3 Ultimate 310 remap is specifically designed to be smooth and progressive, with power and torque starting lower to eliminate wheelspin but hanging on until after 5,500rpm. The test gave a huge 245.7 wheel horsepower (320.7bhp at the flywheel) at just under 18.5psi of boost. Our Stage 3+ Ultimate 322 is designed to be more aggressive, with a big lift in torque nearer 375lb ft and power hanging on well past 5,500rpm. It was not tested on the day, but there is a graph here, and at the foot of this article, showing hub-dyno results of a massive 282 wheel horsepower.

Stage 4 Ultimate 412

Our Stage 4 Ultimate 412 remap is smooth and progressive too, and can be used with or without injectors and with or without a hybrid turbocharger. The power almost mirrors its 310 younger brother all the way to 5,250rpm, where the curves split, the mapping changes and the injectors really take over. At around 6,000rpm there was a gain of 30bhp over the Stage 3 310 and over 40bhp more than the Superchips and JWR Autotech maps. The torque figures again show the progressive nature of the Stage 3 and Stage 4 maps: keeping wheelspin to a minimum gives traction off the line, and the turbo releases a massive 50lb ft more at 5,700rpm than Superchips or JWR Autotech.

Installing a Pumaspeed remap

Installing any Pumaspeed remap is very simple and takes no longer than 10 minutes; the first time the handset-based maps are installed it takes a little longer, nearer 30 minutes. The familiar X2 handset carries two maps of your choice and can be sent anywhere in the world for trouble-free installation. UK customers who can visit the workshop could at the time have a remap fitted via our one-shot system, without a handset, for £275.

One of the many benefits of the Pumaspeed Focus ST225 tuning device is that once the stock tune is reinstalled, the box is free to be used on another car, which gives it real value to a future purchaser. Typical used-box prices on the familiar auction sites ranged from £200 to £300, making it one of the most sensible purchases a Focus ST owner can make.
