Why my car spudders and now don't hear BOV?

[Saint1]

I just installed a 20g turbo on my ej20 motor. I have supporting mods but just never had it tuned yet.
When I am just cruising the car spudders like once for a split second every like 3 mins. When it spudders it makes a squeeky noise for that split second. Also now I can't hear my BOV till I redline and it wasn't like that when I first installed it. I could hear it shifting at like 3 grand.

I don't know what is wrong with it. Could it be because of not being tuned, because I am starving of gas since I didn't upgrade the fuel pump or injectors. Any help would be really appreciated.
Thanks

I honestly would probably recommend you take it to a shop for some advice and work. If that sounds too expensive, take it back to stock and move on.

Ok what BOV do you have.And is the sqeeky noise happing when you are boosting?

Yes. You know your 'supposed' to get a tune after a mod like a new turbo or injectors right? Or at the least have a map flashed to your ecu for your given mods. The stock ECU can't control what you have.

Yea, really. A 20G w/supporting injectors?! On a 2.0? You probably are washing the rings.

GET A TUNE, SOON. Or catastrophic engine failure is in your future.








EDIT...... Seriously. I just read the final pair of sentences from your post. YOu said you have a 20G w/supporting mods. No fuel pump or injectors, is not supporting mods. What are you even talking about, supporting mods? Intercooler? You are going to kill your motor if not your trans first.

And get off the BOV. It's a 20G on a 2.0. Probably doesn't start making boost until past 3,000 rpm even if you did have the proper setup.

So you just think the car will tune itself?How do you think the car knows it has bigger injectors?Take the car to a professional.....................jebus.
