So today I went and got my car scanned and I have p0089 and p0140. 25psi tune along with catless downpipe and Zzp intake tube and high flow air filter. Now I know it's fuel pressure regulator that's messed up but idk how to go about this or what is wrong with it. Help would be appreciated!

 

Btw car drives normal just sometimes after a pull to a stop it bogs down a little. so I'm assuming the engine is not getting enough fuel.

 

I believe I'm going to need a new HPFP but I need suggestions on where to get one.

 

But there's a loud pop sometimes when I let off the gas. Could this be a faulty injector? Or would that result from not enough fuel? No miss fires though? I don't get it?

 

So to update this, just for future reference, cleared the codes and they haven't came back, might have been a hiccup in the system or maybe I'm just paranoid! So, it still runs like like a madman lol. I mean that in a good way.

 

If it bogs when you come to a stop, you might need to clean your TB. Mine did that and sometimes died and lights. cleaned the throttle body and it runs great now. Theres a tutorial on her and its easy to do, take maybe 45 min max if you dont really have experience.

 

The SS/TCs (08-10) its a little more involved than on the SS/SC and we generally don't have the dirty TB issues the SS/SCs had for some reason

 

That is true my car had 65k miles when i had to replace it and the tb was clean

 

p0140 is possibly a bad secondary o2 sensor.

 

Duh, completely missed the fact that its a turbo

 

No longer having a problem guys but thanks for the input! I just think some things didn't get set when my tuner had to redo my tune because not only did my battery die during the tune, my obdii fuse blew so he had to redo my tune just to make sure and he forgot to change those 2 fault codes. Everything runs fine lol.

 

I would give the car a few hundred miles before declaring the issue fixed. A lot of codes take a few drive cycles to pop back up.
