On many occasions performance enthusiasts have debated the issue of whether stock or near stock vehicles will benefit from a specialized dyno tune. Although Diablosport’s pre-loaded Predator makes drastic improvements over the stock performance of any 5.7 or 6.1 Hemi there are still significant gains to be made with a CMR dyno tune. Contrary to popular belief not all 5.7 and 6.1 Hemi’s are exactly the same. Two identical SRT8 vehicles may react very dissimilar to the generic tune that is provided with a Diablosport Predator. These types of inconsistency will not only result in horsepower and torque losses but also sacrifice driveability and safety. To help illustrate this topic I have posted a dyno graph depicting the horsepower, torque and air fuel of a 2006 Dodge Charger SRT8 with modifications including a K&N cold air intake and a 180 degree thermostat. Please take a moment to examine the dyno graph (the baseline pull “in blue” was made using the Diablosport pre-loaded tune, the second pull “in red” was after CMR tuning by Injected Engineering). If you study the graph closely you will notice vast differences in air fuel, horsepower and torque curves.
