Hi if your truck is de-rating most commonly they Deere 8 as a result of failing to perform a successful regeneration because of either a plugged DPF filter will excessive soot buildup or another sensor or other issue throwing a fault code in one of the after treatment system components or possible engine emission components not allowing regen to perform successfully. Most commonly the Derate is from failing to regen and emissions-related. The fault code numbers logged in the ECM memory will tell us what circuits are causing your Derate. As far as your throttle response this could be related to that as a result of that or you could have a separate issue with your throttle position sensor circuit however once again the fault codes will tell us that. Please let me know the fault codes that you have logged and also please remember to take a moment to rate my answer as that is how the site credits my time helping on the site. Five-star ratings in bonuses are always greatly appreciated and we can follow up as needed on here.
