Our Stage 4 APC package #4 which will allow installation to the 1990-1993 900 turbo only. This package is regarded as our "SAAB Owner's Convention" special which includes our Stage 4 Red Series APC, Red Series Fuel Injectors, as well as our new Red Series EPROM(Fuel "Chip") for the 2.4 LH fuel management system. This entails a simple EPROM/"Chip" replacement on the factory BOSCH LH fuel control unit and is a plug-in upgrade (no soldering, etc.), and comes with a full instuctional. The EPROM matches a more progressive fuel curve parameter to more accurately match the turbocharger pressure/boost target of our Red Series APC system and also greatly reduces turbocharger lag! This package is being extended while supplies last during the 2017 season. These upgrades will only fit the 1990-1993 900 turbo (as well as the 1994 900 turbo contertible) and have a total list price of $725 but by mentioning the convention special, we will extend this package for $449.95!
