SymTech Labs fuel cut defenders (FCD) are the perfect choice to protect against fuel cut, a phenomenon that occurs after installing a turbocharger in an originally naturally aspirated (N/A) car. Most engine control units (ECU) in factory N/A cars were not designed to handle positive manifold pressure, so they respond by cutting fuel flow at the injectors. Without a fuel cut defender, boost is out the question.

SymTech Labs intelligent fuel cut defenders (iFCD) offer superior protection against fuel cut, a phenomenon that occurs after installing a turbocharger in an originally naturally aspirated (N/A) car. Unlike other FCD's that eliminate fuel cut, iFCD's let you delay fuel cut, so the engine is protected in over-boost conditions.

SymTech Lab’s Intelligent O2 Sensor Simulator (iO2SS) can eliminate annoying, and sometimes performance-robbing, check engine lights by generating a proper downstream oxygen sensor signal.
