Are your putting out too much boost without enough juice to back it up? These OE RS4 fuel injectors are commonly used with GT2871R/3071R big turbo applications. This set of 4 injectors are a great solution for your 2.0T FSI fueling needs.
Its recommended that these should be used in conjunction with APR's FSI high pressure fuel pump (ES11994). **Custom software and programming is required to run these properly. *
This kit is designed for the FSI engine only. This can easily be found on the engine cover of your 2.0T VW/Audi. It will clearly be stamped FSI (not TFSI).
