if you do any mod your car is gonna get slower w/o a tune! even wen u put your TB on it would have gotton slower....TUNE!

 

the #1 problem is adding the fuel pump without tuning for it.. the car is rich from the factory and now it's unbelievably rich.

 

Dude i just had the same problem, well the sound atleast. However my problem started after i bottomed the car out. Either way mine sounded like a supercharger as well. Check to see if the gasket inbetween your LICP and your turbo is missing, ripped....ect or its possible that the bolts are not tightened enough. I was still holding almost 20psi in that condition.

 

exactly what i was thinking. check to make sure that it is not leaking.

 

You NEED a tune. It has been covered a million times. Get a custom tune and be happy

 

Yeah my car holds boost too and still makes the sound, where is the gasket EXACTLY suppose to be?

 

Yeah im putting back the stock fuel pump soon, one question though, if the car goes rich on an uprated fuel pump, does the car go back to normal when u replace the stock pump? or does it stay in an abnormal condition?

 

I'd love to but we dont have any tuners around here.

 

it'll take some driving around for the fuel trims to get back to where they need to be.

 

I am not understanding. You put these parts on and dont want to get tuned why? At the very least man spend $50 and get a eflash. With just an eflash you'll probobly see a good 20 hp jump.

thats the first good thing to hear all day.

well lets say there arnt any leaks and i change the fuel pump back to stock and the car is still low on power. any ideas what it could be? plus im pretty sure my engine is fine since my car is new.

 

most commonly, probably a boost leak somewhere.

There is a metal gasket with a rubber coating on it. It is located inbetween the turbo outlet and the first LICP. The one that is narrow(maybe 1 1/2 inches), and then flares out to the size of the rest of the intercoller piping. Sorry im not sure of the exact name of that piece of pipe.
