For maximum benefit when tuning the TD5, it is beneficial to increase the boost pressure.
This cannot be done with the car in standard form as the ECU will sense higher boost and go into reduced power limp mode.
Limp mode can be overcome with one of our Boost Boxes, allowing up to 1.35-1.4 bar of boost, which will in turn make the intercooler more efficient.
This is only recommended when an uprated intercooler is installed.

Boost Box fuer den TD5. Nach Turbowechsel und anderem Mapping ging das Steuergeraet immer in Overboost. Die Boost Box von Allisports schafft abhilfe. Montage ist sehr einfach und die Funktion einwandfrei. Da macht der TD5 richtig gute Laune.

Straight forward install and works well – a very slight lag but I think that’s more the ECU response – fitted along with the Allisport Td5 intercooler – nice complementary package
