Info on Further Modifications:

On the N55 engine we reccomend Maps A – D on the tuning box will work well on the standard engine. To go further than this we reccomend several modifications:

• Aftermarket Intercooler: The standard intercooler on this engine works OK at stock power levels, but struggles as power is increased. In order to run Map E on the box an aftermarket intercooler is required. (Click here for IAT Graph on Stock Intercooler)

• Sports Cat or Decat (off road use only): The standard catalyst becomes restrictive at higher power levels. Either a good sports cat or decat tends to yield around a 10hp increase on the N55 engine.

• Aftermarket Charge Pipe: This has zero performance benefit, but fixes a major design issue with the stock engine. The standard plastic charge pipe becomes brittle over time and can fail in service, even when the engine is stock. Replacing this with an aluminium item prevents failure before it happens. 

• Induction Kit / Panel Filter: We don’t recommend changing the Induction system on this engine unless you have good reason to do so. We have tested various induction systems from a variety of manufacturers and have yet to see a system with any appreciable performance benefit. The standard airbox and standard paper element work very well, even at higher power levels. We would suggest spending any funds that you planned to spend on induction on one of the 3 above items instead.
