I went ahead, I couldnt wait anymore...I got myself a GMPP short ram air intake system. I get a sweet deal through my job (Penske) and it knocked the price down to 303 after taxes. But the thing is im not sure if I like it that much. It sounds ok, but it now sounds like the engine is boging and it seems to take more time to get up to speed. Especially in the low end. Am I just loosing it? Or have forgoten to do something? Any help would be very much welcomed.

Thanks

 

dunno bud...i put an injen on my 2.2 and everything works better

 

An SRI should actually be more responsive in the low end than a CAI. You might want to check and make sure you didn't get anything on the MAF during the install.

 

I second that, and I would clear all codes (even if you don't have any) so that all the sensors are set back to the initial configuration so that they will begin to learn the new air flow parameters from scratch. made a big difference when I put all the GMPP parts on my 06 LS -- I thought my performance was worse too until I did this.

 

also i hear the filter sucks, i have the same intake, but i just replaced with an aem dryflow and it works better

 

did you accidently leave something in the piping or the filter??? maybe something got suck up in there or something

 

You got screwed, I paid $247 + tax + $2 for shipping. I think it was like $20 to ship it by itself. Anyway, if shipped seperatly, that still less than $285. And if you don't believe me heres the link.

You might want to look around for something you want next time and maybe you can get it cheeper.

As for the bogging, is the MAF sensor installed backwards?

 

You say it "sounds" like it is bogging, but does it "feel" like it is bogging?? Yes, with a CAI set-up the long intake tract will cause some delayed throttle response but gives gains on top-end. With a SRI, such as the GMPP intake, the intial throttle response should be more noticeable, with a little less gain on top end. If you can't feel it bogging then it's probably just the sound when you open the throttle wide and it gulps in a large amount of air. It's really deep and may just be what you hear vs what you feel.

 

rip off, i got my aem cai for around 250

 

Thats GMPP for you. Less for more.

 

I love that sound =)

 

You check for air leaks?

 

My pricing was in CAD btw and its retail price here is 398. I will check for air leaks, I will make sure the sensor is clean, and I know that there is nothing blocking the pathways. I really have nothing to compare to when it comes to speed/acceleration, it just feels and sounds like it takes more time to get to the higher rpms. It may just be the deeper sound which is throwing me off.

Ive also read around that disconecting you batt will reset your ecu parameters? Clearing dtc's wouldnt do anything either, seeing as they are for diag purposes only. Active or not. (there isnt any running codes that I know of atm) But if it worked for you...i'll give it a try.

 

ya the increase in noise make you feel like your going faster than you really are.

 

When you clear DTCs you also zeroize the sensor data (delete learned data) and the ECM starts learning all over again. It's in the GM service manual. For example if you replace either H02S sensor the factory service manual states to do this so the ECM "learns" the new sensor. If you don't your ECM will learn the new parameters but it will take longer since it has "learned" the old parameters.

I was disappointed at first with all the GMPP performance parts on my 06 LS and my 07 SS/NA -- seemed to have "killed" my bottom end -- but after erasing DTCs (didn't have any either) I could spin the wheels with ease off-the-line.

 

OMG... if this is tru im ging to kill someone...i didnt kno this, and i kno allot about cars... So i could really have allot more power than i currently am seeing? im doing this tmrw.

 

yup, once you reset the ecu you'll be fine.

 

This is one example out of the 2007 Cobalt service manual (refers to resistance learned value):

Its good that you dint pay retail. Those that do are Idoits, or have money to burn.

 

I payed $248 taxes in for my k/n typhoon intake for my g5 gt.

 

I paid 45 shipped for my Ebay Cold Air Intake

 

same 45 shipped works perfect sounds loud/awsome

 

Well thanks alot fella's all of this really helps out. After work today I will be clearing dtc's and I will post my fidings afterwards. Thanks

 

well i cleared my car... idk, maybe i feel a difference... not really.

 

Yup, you all got screwed.

Ebay intake FTW!
