03 Silverado 2500hd 6.0 5speed 4x4.
Within days of buying it I had the PCM tuned by blackbear to try to help the horrific throttle response. It helped some, but is still insane.
Ive ignored it for over a year now, but today decided to actually watch the throttle and see how slow it actualy is.
This might not be a huge issue on an automatic, but on a steep hill, with a trailer, and manual trans, this is a pain in my ass lol. Ive gotten used to it, but it bugs me every time i drive it.
Feathering the throttle, such as taking off under load or on a hill, the throttle just twitches, doesnt even try to open at all.
Everyone tells me i shouldnt be able to tell the difference between DBW and a Cable Tb, but I dont see how thats possible.
Does this video look about normal for you guys or is it indeed slow? Takes nearly 2 seconds to open when the pedal is put to the floor.
