Ok, i think i may have "teh infamous WRX mod"

whats happening, (CHARGE PIPING IS NOT BLOWN OFF, AS IM STILL MAKING BOOST AND IT CLIMBS!)

im on the gas about 1/2 throttle at about 4K the car studders, Like it hits the rev limiter, REALLY hard jerk

ohh man..

please tell me its not the WRX mod

Oh.
info on my car
07 LS 22K miles, boosted and TUNED! with a T25 Turbo running 11 pounds

 

well, you would sound like a WRX for starters...
Im thinking you have MAF issues though. Running with no MAF causes hardcore misfires at higher RPMs

 

sounding like a rex wouldnt be a bad thing

 

Well i have NO exhaust what so ever, i have a 90 bend off the turbo thats it
so i cant really tell to be honest

and i am running a MAF...

idle was normal also..no jumps or anyhting

 

Well... your car still makes noise...

does that noise sound like a WRX?

If not... then you didnt do anything bad.

 

man..idk

exhaust note may have changed..i dnt think so tho

hopefully im freaking myself out

 

dood this happened to me too today in 1st gear twice. no check engine light, no difference in sound etc etc. i dont know what happened

just because the MAF is there doesnt mean its working correctly.
it doesnt hurt to check it. ideally, if you have a friend with a cobalt too, swap MAFs and see if the issue is still there

 

i do..well its at the shop getting my exhaust finished

hoping its something easy :/ keep the stuff coming bout whati hsould check

 

compression test

First off, it's WRX SOUND, not mod. It just means that you are missing, replace your spark plugs and pray that it goes away.

Yes it is, wrx's sound terrible. It sounds like the car is missing like crazy. It's the worst sound in the world for every other type of car out there cause it means yo **** is FUCKED UP.

smartest post in this thread.

I don't know your exact problem, but you could use a full downpipe with a turn-down.

 

Idk man, a wrx with an aftermarket header sounds amazing.

 

I wonder what a turbo cobalt would sound like with unequal headers like a WRX. granted its not a flat 4.

im still not totally sure on why exactly subaru did that.

 

i would imagine its cheaper to manufacture that way. sounding unique would be an added bonus for them too.
