do yall 6.5 guys hear yalls turbo. mine is so damn weak and wont pull a load over 45 but i never hear the turbo. maybe its out.

 

Turbo solenoid. Yes I hear my turbo I have strait pipe on both of mine but you should hear it. Start the truck up and see if you can move the wastegate. If you can it is ether a bad line, turbo solenoid or a bad vacuum pump. I would take the vacuum system off of it and put a mechanical one on it.

 

if you got a stock exhaust and stock air intake then you wont hear it. check the specs on how much vaccum the vaccum pump is pulling and test it. get a boost gauge and see how much boost your making. 7-9 stock is about right and anything over 12 psi sustained will throw a boost code unless you reflashed your computer

 

yea when i bought my truck i found that the vacuume line was just not connected, you just need to follow the lines

 

all connected. have vacuum at turbo. wastegate moves. took off the air filter side at turbo. revved up and no whistle. this thing has no power at all. and only getting 7 mpg towing.

 

When you start the truck you should not be able to move the wastegate. The wastegate controller could be bad to.

 

i have a spare turbo. i may need to put it on an see if it does any better.

 

What year is the spare turbo off of and what year is your truck? If you have vacuum to the turbo vacuum canister on the side of turbo is probably bad.

 

I would put your spare turbo on, in I were you. What can it hurt.

 

the turbo is off a 93 and my trucks a 98. is this a problem
