I thought that during WOT shifts the computer pulls timing or fuel or something to lessen the harshness of the shift? I remember reading something about that.

Anyway, ever since I got my Borla put on it the WOT 4-5 shift sounds like a long blatty fart and it's embarrasing. And I suspect it's the way the transmission shifts because the RPM's jump about 200 - 300 and hold there for about a second before going into 5th. And it's during that time when it sounds like the fart.

Get rid of the torque management and it should go away. Maybe.

 

Hey, it's a backpressure/fuel thing. I've been riding straight pipe and now MINE does that exact same thing. It's not bad for you, but if you don't like the sound (I think it scares people and it's awesome) then just *beating a dead horse* tune it, or redo some piping.

 

Here is what my truck does. At 5 seconds into the video it 'burps' where the pressure just dumps out when switching into 2nd gear.

what is happening is a w.o.t. shifts the truck will lose some power when shifting, causing this terrible noise, i never exsperienced it with the stock system, because of the resonators, but now i have the same issue. i dont mind the noise. it is kinda hard to hear it when the truck shifts. the tire chirp takes away the noise, but that sound is what it is. also you should hear a hemi, when it does it. sounds like some shoot a horse

 

I would LOVE to know how to get rid of that torque management crap. Even with an auto trans it should help these trucks a ton.

 

won't the tuner adjust it? Or does it require the stealership's tool?

 

Don't have a tuner, so not sure there. Talked to the service manager last year though about trying to have them cancel it out and they said they won't/can't because of some warranty bs. :/
