here it is. its a 2004 chevy silverado 2500 4x4 6.0l gas

after i select scan tool and turn key on it just has a spinning icon and never goes to any other menu. anyone know what it could be?

I can understand your frustration, but we have literally tuned 1000s of trucks just like yours and never seen issues like you reported.

We'd be glad to take a look at the tunes if you post them up, new thread would be a good idea.

Thanks

there are issues like mine in this forum or at least ...

shifting problem solved! i restored the stock tune. i wish i could get a refund for this tuner. worst money i have ever spent. if you have a 2004 chevy silverado 2500 crew cab 4x4 with the 4l80e tranny do not by this tuner it will not shift right. im just glad it didnt tear up my tranny.

there is still a big pause from 1st to 2nd when i am at half throttle. 2nd to 3rd to 4th seems fine. if i am giving just a bit of throttle it seems fine. not sure about wot. what do you think that could be?

anyone?

it is already disabled in this tune.

if it was already disabled then doctortuned must have done something different cause it does seem to shift a little firmer.

if you are looking for the same fix please post the backup file as well.

i think he posted that for me.

heres my tunes.

my 2004 chevy silverado 2500 6.0l doesnt shift any firmer no matter what shift pressure i have it set at, does this mean the torque management is still on? i see it in the menu but there is nothing there when i select it.
