MAXD Custom TUNING Available Now

The MAXD-OUT Focus ST225 330bhp power kit

MAXD custom tuning: more power on less boost for the Focus ST225.

The Pumaspeed PS330 kit was, for many, the top-of-the-line package for every ST225 on the standard turbo: a full bolt-on list and the very impressive Pumaspeed U322 or U412 mappings, making one of the quickest street cars around. Then MAXD-OUT asked if they could make it better.

The next level by MAXD-OUT

The masters at MAXD-OUT suggested they could enhance the now-old mappings to create more power for less boost, if we let them loose on a Focus ST225. Eager to oblige, we supplied a car with a Superchips Stage 3 Plus fitted and all the normal bolt-ons: Milltek Sport 3-inch de-cat, Milltek Sport 3-inch downpipe, K&N 57i air filter kit, R-Sport Stage 1 intercooler, Milltek Sport Ultimate 3-inch cat-back exhaust, Pumaspeed tapered inlet plenum and 440cc injectors.

The car was custom-tuned inside a day and all the data and power graphs taken. With crucial increases in ignition and fuelling settings that had never previously been touched, we think the results speak for themselves.

“MAXD power 327.1bhp, up 17bhp at 5,800rpm on the previous U412 peak. MAXD torque 502.8Nm at 4,308rpm, up 23Nm, and up 30Nm at 3,000rpm”

With a stronger mid-range and top-end power that holds on far longer, the car is transformed into the ultimate small-turbo flying machine. For the very best in mapping, the MAXD-OUT Pumaspeed 330bhp kit using the new Stage 2R (also known as M440v5) is ready for you, and all the new maps are available on the ST225 MAXD tuning box.

• Focus RS Mk2 440cc injectors
• 3-inch de-cat and 3-inch downpipe
• Milltek Ultimate 3-inch cat-back exhaust

Power: 327.1bhp at 5,811rpm, up 17bhp at 5,800rpm. Torque: 502.8Nm at 4,308rpm, up 23Nm at 3,000rpm.

What the data shows

• Boost spool: the boost comes on much earlier and stronger thanks to the added ignition.
• Boost peak: it peaks at 1psi more than the next most powerful tune.
• Boost mid-range: lower and safer boost across the mid-range and to the redline.
• Air-fuel ratio, low revs: to promote spool, the AFR is kept a lot leaner than previous tunes, which also gives far better economy off boost.
• Air-fuel ratio, mid and high: perfect AFRs all the way to the redline.
• Wheel power: typical transmission losses are calculated at 15 to 19%. Measured wheel power was 284bhp; at 19% that is 339bhp, at 15% it is 326bhp. Either way, pretty impressive.

All of it is available by mail order or workshop-fitted at Pumaspeed.
