Guess what? Its back and worst.
Car wouldn't boost past 5lbs. problem would come and go, all stock GM stage 1 kit. Autozone read code said it was the turbo valve was stuck open. Took it to dealer they replaced the vacuum tank. Car ran fine boost to 23lbs. Took it to Snyapse Turbo to have turbo upgrade and tune. Car did same thing again, 2 times in 800 miles. Turn car off, start it back up and it's cleared. Took to Chevy and they want to charge me for troubleshooting problem because of upgrades
I will change the vacuum solenoid and see how that goes. Don't think it's K&N filter as I had one before stage 1 upgrade and had no problems. Don't think it's a leak in piping either. Will let everone know how I make out.

Just got done installing the AEM revised intake. Here is a photo.


so far no CEL or other issues to indicate. Car sounds like a dog sneezing when you shift hard between gears into higher RPMS. LOL

Ok so my new sensors are in (the mechanic said they basically just got me a new kit) so hopefully they reflash it too, altho they did say they did not boost leak test it, which they will do when they do the install. Also Im going to have them solder the wires. After all this, the car should be back to 100%, instead of the ~80% percent it feels like its running.
it is going in on tuesday 8/10

Ok guys got rid of alot of the flutter last night by bypassing the vac tank. There is still a tiny bit of flutter. Something wierd tho is with the k&n on I hear a high pitch squeel coming from my intake when I'm in max boost. It's not the intake it's self, it sounds like it's coming from the turbo? What could it be? Could the bpv be weak and not holding shut at full boost. Could that be why my car doesn't pull like it used to. That would cause a boost leak right?

Ok....what's the best way to make sure it's seated because it's hard to do. Any pointers. The noise isn't noticable with the stock air Box on, just with the intake because the intake magnifies so much. I'll see if I can get it seen to this weekend.
had the same problem as in video
I had the same issues as the car in the video as well as all the others. PURGE SOLENOID is the culprit guys had the diagnose done. 33 dollars and 5 min later 24.5 PSI and flying. Drove to airport and back MPG went up to 33.3 and was climbing till i hit city. Was amazeing. I reccommend everyone who is haveing this problem get a Purge solenoid from local dealer asap.
PURGE SOLENOID, lemme know if this fixes this issue for you guys becuase it did for me.

Well after bringing up my forum (https://www.cobaltss.net/forums/2-0l-lnf-performance-tech-153/whats-causing-my-car-flutter-216926/) about the fluttering issue with 5800 miles now, it came back bitting me in the ass in a bad way. My car is starting to **** me off with the bpv going bad. I was leaving my street merging onto incoming traffic. I hit the gas in first gear and felt something awkward, then hit 2nd gear my car wasn't boosting as fast in 2nd gear as I expected and saw my boost gauge hitting 5psi only, instead of 20psi normally. So I let off the gas and the flutter noise occurred and kept doing it to me the next couple of minutes. After 20 minutes, it went back to normal and never occur again. I was hitting my boosts level normally at 20-22psi. Now I'm going to the dealer to get it check out. Why is this happening to me?
On the way home from work today I felt it again. This time I knew something was wrong so I waited until I got to the main street (somewhat back-road) that leads to my neighbourhood. I put the gas absolutely to the floor in 2nd and watched the boost gauge stop at 0. I swear the car had about as much power as my g/f's Aveo running on 2 cylinders, it was ridiculous it went nowhere. I tried 3rd and instantly felt the pick-up I was expecting, though because of where I was I couldn't open it up. Friend also suggested I check the purge solenoid but first I'm going to run the same test in the morning since it seems to happen one start and not the next. It'll be off to the dealer, first thing I'm recommending they check is the solenoid. If it were a boost leak I would expect every gear to fall no its face, same if the TMAP was rubbing/moving. I have had 0 engine codes show up so I'll see how it goes tomorrow.
well do...! glad someone said it better than me. I attend to exaggerate and not make any sense. If my car keeps it up in the longterm, goodbye I say. Take out the aftermarket parts and sell it, bring it to normal condition and get myself a reliable vehicle like the 370z or a V8 if I ever get in the car sales, which I'm applying for.
Its been mentioned before, the 370Z's have brake problems. Car and Driver had the brakes fail within the first couple laps and put a brand new 370Z into the wall at Virginia International Raceway. No other cars in the test, including the SS T/C, had any brake problems at all.
Nissan's VQ is also a pile, they are very harsh revving engines (V6 w/o balance shafts), and they sound quite raspy and have a propensity to burn oil at higher mileage. Its a good looking car, but I would never buy a Nissan.
If you want a fast, reliable car, get a '11 Camaro or Mustang.
but if I had the money, I'd go for the less powerful Challenger RT... because as I've understood it the SRT is a fully loeaded car - whereas the RT is a more stripped down car...
plus te cost savings can go towards a SC kit or something, if you really need the extra power ~ and then you'ld likely be more powerful than the SRT, while still in it for less...
Challenger is nice, but it just can't touch the GT or SS in the handling department. The T/T drives like a boat compared to those two.
The Challenger R/T is just more of a boulevard cruiser than an all out performance car, which some people may actually prefer.

I've been having loss of boost as well. My loss of power happens on start up though. If I turn the car off then start it again it goes back to normal. It finally gave me a code p0236 yesterday so I dropped it off at the dealer again. They said they would check everything this time!
unfortunately these days the manufactureers look at cars this way;
bigger/more powerful engine = car fully loaded with options
I like the RT because it doesn't come with all the extras the SRT comes with...
Then again if I could have I'd have ordered my SS/TC as essentially a base model - no onstar, no p/w, so sunroof, no spoiler, no additinal airbags, ect...
but that's just me...

if anybody said Mustang like the V6 (3.7 or 4.0), guess where the transmisson is made at?

HELL NO! Your not seeing me driving in that. I call that the Chinese Fordstang. I wish I took a picture when I was at the Ford Dealer looking at Mustangs and price stickers and finding where the parts came from, until I saw China on the transmission and USA on the engine. Here is a forum about the tranny made in China, I kid you not http://www.allfordmustangs.com/forum...ade-china.html.

I suspect you will see more Chinese parts as time goes on, in lieu of Hecho in Mexico.
I agree w/ the profit side in the US !!

Now, back to your regularly scheduled thread.
