coming home from work yesterday I went to pass a slower truck, when ii got on it the boost went to 28 pounds and then hangs there. It kind of makes a fluttering sound. Everything pulls real strong in till it peaks. I used to get up to 48 pounds did not here any pop no weird noises either just wont make full boost. any help

 

What kind of mods do you have?

What are you reading boost with?

Fill out your signature and let us know what you are workin' with...

 

sorry just updated my signature but i have a bullydog with outlook monitor

 

I have no first hand experience with electronic gauges...but I've read that they are not accurate reading boost over a certain psi...

FWIW, my boost will max out at about 29-30#'s, and that's with a stock turbo.

If you still have your stock turbo, there is no way you want to be spinning it up to 48 psi...I think anything over 35 or something like that is a waste, and can lead to big problems...

You might want to pull your intake off and check your turbo if you have any concerns.

 

i believe our turbos put out between 28-32#s of boost stock. i think our turbos can make around 40 and may be able to produce more but i think it becomes inefficient after that. i'm not totally positive though.

 

sounds like a leak...check all your intercooler line connectors
