Chip tuning for Challenger MT 655 301hp (221kW) 1295Nm ECU
Challenger MT (I) 655 301hp (221kW) 1295Nm — sports diesel engine of the agricultural segment of the Stellantis group (США, 1925). Stage 1 chip tuning raises power from 301 to 355 hp (+54 hp, +18%) and torque from 1295 to 1570 Nm (+275 Nm).
The Challenger is Dodge's iconic muscle car, revived in 2008. The Challenger uses Hemi V8 engines (including the Hellcat and Demon). DPF/SCR with AdBlue is standard on modern Chrysler/Ram diesels. On high-output Ram diesels, Stage 1 is especially felt in the torque gain. Chrysler uses Cummins diesels in the commercial segment (Ram).
The US Chrysler community has a large pool of ready-made Stage files. HP Tuners is the leading tool for Chrysler/Dodge. High-output Chryslers are Hemi V8s with solid headroom for Stage 1.
