E46 M3 Shark Injector (programmed for headers, no cats)

Part #: N4S54KXX

RACE VERSION Performance Software for E46 M3
The Race Shark Injector software has been specifically designed for race cars running headers and a racing exhaust with no catalytic converters. We have used this software with a number of different headers with great results! We recommend the factory BMW Euro headers because the fitment and quality is excellent and they produced a lot of power on our dyno. Using a set of headers without a catalytic converter will surely cause a Check Engine Light which will lead to problems during tech inspection and may disqualify you from the racing series you’re in. The secret to the Shark Injector Race software is that it 'turns down' the readings from the rear O2 sensors to eliminate codes for 'cat-inefficiency'. The DME will then rely on the front pair of O2 sensors and the stock EGT sensor only.

This Shark Injector also includes Conforti Performance Software for a substantial boost in power and torque! The stock software is a little restrained and Conforti reengineers it to be more aggressive. He tunes his products on the dyno where real power and torque gains can be established. This software also includes:

8100 RPM rev limit (8600 RPM available)
top speed governor removed
quicker throttle response in non-Sport and Sport Mode
smoother torque curve for better driveability
standard 91 octane (N4S54KAT) setting or a more aggressive 93 octane (N4S54KAO) version
