• What is a Stage 2 Remap?
• A stage 2 remap requires a certain level of hardware depending on the vehicle. However, there are some basic requirements that we will touch on that could be required as an extra for a stage 2 tuned car on certain models.
• Intercooler Upgrade
• A front mount intercooler is something that would be required at this level of tuning due to the increased boost pressure and timing advance by the ECU remap. This, in turn, will create more heat, meaning you will need to upgrade the intercooler to counteract this increase. An upgraded intercooler has a much greater core construction, a larger surface area, and potentially a bigger inlet and outlet from the intercooler.
• Exhaust Upgrade
• An aftermarket exhaust system is another key component of a stage 2 remap, and in most cases, a full turbo-back exhaust system is required. This will comprise of a decat or sports cat downpipe, depending on your intended use, coupled with an oversized cat-back exhaust. These will require a remap to stop the trigger of an engine management light.
• The pipe diameter of your exhaust system for stage 2 remapping can also be very important, depending on several things such as power expectation, engine displacement, turbocharger, size, and so on. The turbo will also require some back-pressure to operate optimally, however, too much can cause issues, with excessive exhaust gas temperatures which may result in damage to the engine. So be sure to take the advice of your chosen tuning company.
• Air Intake Upgrade
• It is imperative to feed your turbocharger with well filtered, cold air so the intercooler doesn’t have to work as hard to cool the heated air passing through to the throttle body.
• In most cases, the requirement of an aftermarket induction kit, such as an R600 for VW remaps or an ITG Airfilters induction kit, will be the go-to choice. However, for the BMW remaps range we have achieved stage 3 figures with the standard BMW airbox, they are surprisingly efficient!
• Induction kits are also commonly referred to as stage 1, stage 2, and stage 3, denoting what level is required to match the remap you are aiming for. Induction kits are often mass-produced these days, making them relatively cost-effective, which is good considering they are essential as part of a cooling upgrade ready for a stage 2 remap.
• Other addons that may be required (vehicle specific).
• An upgraded high-pressure fuel pump offers extra fuel to some of the modern-day direct injection engines require for a stage 2 remap. This means you will either need an Auxiliary fuel setup or an upgraded high-pressure fuel pump, which will keep up with fuel demand due to the consumption and allow for a more aggressive boost strategy.
• Some applications, mainly from VW / AUDI group, can benefit massively from an upgraded turbo elbow, turbo muffler delete, and upgraded intake pipe.
