I noticed just like everone else says but i really noticed it after the headers, you could hear the timing being pulled in the exhaust sound, it sounds like a stout motor without it but if its there it will sound like an old emmisions laden truck motor from the late 70s when it shifts if you can picture that. I def noticed a good improvement in feel at least with it removed, not sure of any 1/4 mile results

 

simultaneous pressure on the left and right pedals will tell you right away if its still there or not

 

my truck would spin the tires right when i got it before it was tuned. so i cant really tell anything?

 

in HPT under "torque management" in the "engine torque" section, there is a spot for "torque delivered: shift in progress, it is at 13% stock, is that what I should increase to reduce torque management and get more power to the ground during the shifts, etc?

 

I have taken all of mine out except a little bit kicks in right before and after the shift point...

My truck does the same thing with headers, I think becuase it has no cats when the timing gets pulled back on the shift it makes a pop noise that sounds really bad. I wish I had cats now becuase I think it takes out a lot of that noise and makes the sound more smooth.

 

That might be from running rich.... Mine does that a little bit when it is cold...

 

Yeah, but it also does it when its warm. Another truck with a small block gen I 406 with LTs and no cats with flomaster dosent do it so I dont know.

 

bringing this back from the dead...

On the 04 crew 6.0L we have it will not spinn the tires with 4:10 gears in the rain... the dealer said the lack of power ( its real slow under 50 mph) is do to the torque management.

On a side not a friend bought HP tuners to see if we can turn this crap off. He said the format on the new hp is different than on his 1500 silverado and 98 ls1 camaro..

 

they took out all of my tm finally and its a lot better!!!! way more smooth doesnt make that damn noise it used to make before.!!!
