Just got my car back from the tuning shop.. Its been 3 days and Ive been through 2 coil packs and now under moderate to heavy accelleratin theres a LOUD screeching noise coming from the engine.. The car is running fine, So maybe its some type of hose lose or something. Any ideas? Hopefully something I could just fix myself..

 

Pull off the serpintine belt and run the engine and see if the noise is still there. That will tell you if its belt driven or not.

 

I just realized the car only does it when warm.. Basically once it gets close to halfway on the coolant temp gauge. What would this point to?

 

poor some antifreeze on ur coolant and see if it helps. if not, do wut auditech79 said. if the sound is still there again, u got a diff problem

 

loud screeching is typically a belt, bring it back to the tuning shop and complain say you had all these problems since they worked on it. htey can figure it out probobly for free.

 

Well I found out what it was, and figured Id post it in case someone has a similar problem and searches for it. The intake hose that connects to the turbo was a little loose, so under moderate-heavy boost air was leaking out making the squealing noise.

P.S-Why everytime I try to post pics it says 'Error saving file to disk"?
