OK so in putting on a LS4 TB everything is on and theres this queefing sound, or like when your farting so hard for that little bit of air and it just makes a high pitched sound. It wont go away unless you take the intake pipe off the TB , then for a second it goes away then the car sputters because its not getting a MAF reading and shuts off

We are using the Rebel Adapter plate and I changed the value in HP tuners that needed to be changed to 4500, is this not correct or is it different for a saturn redline?

Help needed asap

it's a throttle body queef. rofl check all your connections? everything tight? everything sealed right etc?

:lol:

I can't stop laughing about your description. If I were you, I would check the coupler you are using for cracks or holes. Sounds like you've got a leak. How does it run when it's queefing? HA HA HA

Seriously though, does it spudder, stall, rough idle, anything like that?

Its a brand new coupler it does it with both of them

it runs rough, but is idling better with the new coupler we just got, but the noise is more constant

all i changed was the input area or scaler whatever its called that was 2895 and changed it to 4500 as i have seen in previous posts, no MAF or VE changes

I think that is right, and I definately don't think that is your problem. You can't locate the origin of the queefing? Don't feel any vaccuum coming from anywhere around the connections?

maybe the adaptor is bad

Did you reinstall the o-ring gasket when you installed the TB?

maybe you need a new gasket?? Something sounds like it's not sealing properly or something

take it to the dealership and tell them you hear a queef coming from under the hood.

The TB is used, it looks ok, I cant see anything wrong, not sure if you can see if there is anything wrong is there something that i should be looking for

well i kept the orange gasket on the supercharger and then put on the plate to match what the supercharger outlet looks like with the notch thing at the bottom and the black gasket on top of it facing the new throttle body
