The E torque DT rams respond well to tuning as do all 5.7 Hemis. There are genuine gains to torque and fuel economy as we can take advantage of the variable camshaft and variable intake manifold runner to optimise torque and mid range power. Tuning alone without any other engine performance mods can yield around 40Hp but when coupled together with proper ceramic coated high flow headers and Cold Air Intake can get as mush as 70Hp+ at the wheels on wide open throttle.
Headers and intakes can be added down the track at any stage if you want to just get the tuning done 1st, but ultimately it is technically better to get the hardware done before the software.
The initial tune cost factors in the installation of the FCA Security bypass cable, tuning credits for engine and auto PCMs. Any tuning requirements after this is at a significantly reduced rate. We require the vehicle for 2 days normally if just tuning.
Have you had an exhaust system done on your DT but cant stand the noise when 4 of your 8 cylinders deactivate??!! Then you need tuning to turn it off! The vehicle does drive smoother and more responsive and doesn’t seem to jump down gears prematurely when the 8 cylinders are providing constant and smooth torque to the auto.
