2019 Dodge Challenger SRT Hellcat – 2.85″ Pulley, In-House PCM Unlock, and Tune

Challenger | Dodge | Make : February 12, 2022

When we say we’re living in the Golden Age of Internal Combustion Engines, we often cite the Hellcat line as a prime example.  Seriously, what’s not to love about these cars?  You know, unless the magnificent sound of a roots supercharged 6.2L Hemi hammering the rev limiter mid rolling burnout does absolutely nothing for you… in which case, you’re in the wrong place.



But clearly, David is on the same page with us, and brought his gorgeous F8 Green 2019 Dodge Challenger SRT Hellcat for our Stage-1 package!  This package is proven to take these cars from a baseline of 640-670whp, up to around – and in many case well over – the 800whp mark, all on 93 octane, without any compromise whatsoever.



Now, while David liked the sound of our package, he likes the sound of his stock intake too, and decided to forego the JLT Performance air-intake system.  While this seems like a small adjustment, it is responsible for 30-40whp, and definitely shows up on the dyno.  The remainder of our Stage-1 package still showed up and did its job perfectly!

Even without the extra help of the JLT Performance air-intake system, output still jumped up over 100whp to 771.65whp & 743.55lbft, at a perfectly safe boost level of 15psi!  Usable power all over the curve.
