2003 Dodge Neon SRT-4 MoPower Stage 2 ECU Flash

The Dodge Neon SRT-4 was one of Dodge’s most iconic sport compacts. With its 2.4L turbocharged engine and TD04 turbo, it quickly became a cult classic. MoPower Calibrations has developed the ultimate Stage 2 ECU Flash for the 2003 Dodge Neon SRT-4, pushing performance even further than Stage 1 and delivering serious power gains.
