2003 Dodge Neon SRT-4 MoPower Stage 1 ECU Flash

The Dodge Neon SRT-4 was one of the most exciting performance cars of the early 2000s. Equipped with a 2.4L turbocharged engine and TD04 turbo, it quickly became a cult classic. MoPower Calibrations has developed the ultimate Stage 1 ECU Flash for the 2003 Dodge Neon SRT-4, unlocking extra horsepower, torque, and that aggressive turbo personality the SRT-4 is famous for.

Important – ECU Core Requirement

The 2003 SRT-4 ECU was a one-year-only unit. To flash our calibration, you must provide a 2004–2005 SRT-4 ECU core. Ship us your working ECU, we’ll flash it with the MoPower Stage 1 tune, and return it to you. We do not stock ECU cores.

Stage 1 Features

• Boost raised to 16–18 psi
• Gain of 15–20 HP and 20–30 ft-lbs torque
• Improved turbo spool and throttle response
• WOT shift boost hold feature (PCM-controlled boost)
• Aggressive exhaust decel popping
• Modified fan temperature settings
• Adjusted secondary O2 sensor algorithms
• Refined spark and fuel maps for safe power

Perfect For

Stage 1 works seamlessly with stock injectors (2004+), stock turbo, and stock sensors. It also pairs well with minor bolt-ons such as intake, exhaust, or catless downpipes.
