Dodge Challenger ECU remapping
13 files available
About remapping
The Dodge Challenger accounts for 13 files in our catalogue, split between the 6.4 and 6.2 V8 of the SRT and SRT8 versions and the 3.6 Pentastar V6. It is an American muscle car in the most literal sense.
Stage 1 makes up 6 files, with 4 pop and bang and 4 speed limiter removals. The ECUs are GPEC2, GPEC2A, GPEG2A, NGC4 and Siemens/Continental references. Being naturally aspirated, the gains here are modest by nature.

How much does a naturally aspirated V8 gain?
Considerably less than a supercharged or turbocharged engine — there is no boost to adjust. Expect refinement in delivery rather than a large power figure.
Why so many speed limiter removals?
These cars carry an electronic cut set for their market. Note that legal speed limits on public roads are unchanged by any electronic work.
Is pop and bang legal?
It is not permitted for road use in Spain: it alters the exhaust's approved behaviour. It exists for track and closed-circuit applications.
