People like these types of tunes because they are easy to install and get power from them immediately. The piggyback tune “tricks” the factory ECU into producing more power by increasing boost or running a more aggressive ignition timing.

So what is the difference between a piggyback tune and a flash tune for your MK7 GTI? MK7 Piggyback TunesĪ piggyback tune plugs directly into the ECU. We want to jump into the differences before getting into the different types because it is a very hot topic when it comes to tuning a car. When researching, you will mainly come across two different tunes: a flash and a piggyback tune. We recommend replacing these every time you replace your spark plugs. Bad ignition coils can cause rough idling, engine misfires, and so on.

MK7 GTI OEM Ignition Coils: ignition coils provide power to the spark plugs.

Install these before tuning and replace them every 15,000-20,000 miles.

1-Step Colder MK7 GTI Spark Plugs: any tuned GTI above-stock boost levels should be using 1-Step Colder MK7 GTI Spark Plugs.

Recommended to replace every 40,000 miles.

OEM MK7 GTI Spark Plugs: use these OEM spark plugs for stock or modified GTI’s that are running on stock boost.

If you are planning on sticking with OEM spark plugs and your current ones are more than 15,000 miles old, we also recommend replacing them before modding.
