The badge alone is not enough: in this generation, the same engine designation came in different power outputs, each with its own calibration. Check the power output in your registration document and find the matching row.

What makes the Dodge Challenger special
Dodge Challenger remap: V6 or Hemi V8
From 2008 to 2023 the third-generation Challenger was built as a rear-wheel-drive coupé. It was not sold through Dodge's UK dealer network: cars here are mostly left-hand-drive US imports, identified by model year and trim such as R/T, SRT 392 or Hellcat rather than by a Mk number. Two versions account for most of the interest in a Challenger tuning box: the SXT with the 3.6 V6 and the R/T with the 5.7 Hemi V8. Both take the GAN GA+, rated at up to 12% more power, starting from 305 hp on the 3.6 and from 372 to 381 hp on the 5.7.
The 6.4 Hemi in the SRT 392 and Scat Pack is the biggest engine in the catalogue, at 485 hp. The supercharged Hellcat has no separate Challenger row; look for the same engine under the 6.2i of the Dodge Charger/Magnum. Imported Hellcats do turn up in UK listings, so for those cars the import specification and parts compatibility are worth checking first.
Dodge Challenger remap: common questions
Dodge Challenger SRT 392 remap: how much does the 485 hp car gain?
The GAN GA+ lifts the 6.4 Hemi from a standard 485 hp and 644 Nm to 524 hp and 696 Nm. Treat these as catalogue gains for this engine type, not a dyno reading of your own car.
Which GAN box suits the Challenger SRT8 6.1 and the 3.5 V6?
Both take the GAN GA+: the catalogue lists the 2008–2010 SRT8 6.1 Hemi at 425 hp and the early 3.5 V6 at 250 hp, both American SAE ratings.
Should I declare the GAN box to my insurer?
Tell them. A tuning box raises the output, and in Britain that is a declarable modification like any other performance change. Policies differ, so a quick call to your insurer before fitting is the safe route; the figures they will ask for are the stock and GAN outputs listed here.
Is a tuning module the same as a Stage 1 remap?
Not quite. Stage 1 usually means an ECU remap without replacing any parts. The tuning module also works without replacing parts, but it does not change the ECU software: it adjusts the sensor signals, comes off in about a minute, and the OFF button in the app restores the factory settings.
