Hey guys, I drove my car alot today. At first she was rippin shit at about 13psi...untill about 4:00 when I had to go to work.

The car felt VERY sluggish and slow. My boost guage read only 8 pounds at the most and rpm went up very slowly, it was even 6psi a few times at WOT. I felt no jolt of boost what so ever and it felt like it was insanely heat soaked but it was cold outside , and it carried on for the rest of the night being slow ass shit and I have no idea why. It did this to me before I parked it for the winter, I got it tuned up and it ran great, now its starting to go down the drain again. It idles fine, doesnt burn anything its just the Turbo I am worried about in this case . Ill see tomorrow morning when I head to work what it boosts at. If it goes back to say 13psi what could this be?, or if its running really low again, this sucks...anyhelp would be greatly appretiated

could be a boost leak, have you checked all your hoses/couplings?

Might do it after work. Can I spray soapy water on the UICP, rev it and see where it bubbles...or will that work

I can hear it spooling and all that, Im just not getting it to the ground at all.

yeah start with the leak ive had my hose blow off at 10psi at the throttle body after that i would check all the vacuum lines between the bov and boost controller for leaks

Make sure you look at the vfaq on how to make a leak tester and how to do a proper test. The way you described it in one of your replies will not work.

www.vfaq.com
look under the intake section.

while your doing that leak test check the turbine for shaft play.

Make Sure All Your Intake Adjustments Are Set As Should Be, And Make Sure It's Getting Enough Air, Period.

It's probably just a leak, that's what it usually is.

Well today it was just fine. Hitting normal boost and was fast again...wtf .

Well I wish I could stay and chat, but I gotta go get smashed tonight haha, have a good night boys

did you check to see if the wastegate was still connected?

Your car may have been detonating/knocking immensely. When the ECU sees too much KNOCK it activates the Boost Control Solenoid to bleed off much more boost even upto 6-8psi and pulls your timing to save your motor. Thought you may want to know that.

Wouldn't hurt to do a boost leak test and hopefully you are not running crappy gas in it.

Hmmm that is a Very good suggestion. Im running 91 octane with 2 bottles of booster, So she isnt too bad.
