just curious is it really that bad to run an aftermarket intake on stock tune.. I know it messes with the airfuel and I have been doing research but is it really that terrible? I know all intakes are slightly different such as the dejon sri the hahn, injen, and now the new k&n but it makes the car sound so much better. Just curious on different peoples views..

 

Its not that bad to do for a little while like a month or two, but eventually your going to want it tuned for properly so it can work properly.

 

True dat ^

 

Its terrible, People/ cops/ street racers always looking at you when you accelerate. Its really an attention getter. I wouldnt get an intake unless you want the attention and like to be noticed.

 

^ Strange response.

 

I know its loud I have had one on my car before im talking about more with tuning wise though

Tuning= Warrenty gone what about an injen intake with stage 1?

 

Term mentioned someone with the Injen intake loosing midrange power on the dyno, read the Intakes sticky.

If you are not going to tune for it, the new AEM Term is testing or the K&N SRI may be your choices.

 

Say you do run an intake for awhile with out tune. What would the consequences eventually be?

 

Long term fuel trims shift, may or may not cause drivability issues. Dejon untuned does, old AEM CAI untuned does from my personal experience. When the fuel trims are out of whack it takes time for the ECU to compensate on every throttle change. While it is hunting for the proper A/F ratio it may misfire, lurch, ect.

The untuned Dejon I had lurched at part throttle pretty bad going in & out of DFCO. (Decel fuel cut off)

The old AEM tuned or untuned had compressure surge at cold start & some drivabilty issues.

When I had the Hahn I was tuned for it and it was fine.

 

It is not that loud LOL. My exhaust is easily twice as loud and hardly anyone notices unless I am at WOT.

 

You do know that you can still keep ur warranty if u tune ur car?

Depending on the warranty work gettin done all u have to do is flash it back to stock. But I never do, and probably never will lol

 

get the k&n sri and you wont have issues on the stock tune or gm stage 1.

 

Do we have proof of this?

 

yes, have you been in the k&n thread? when installed properly the trims are actually very good. The stock airbox isnt perfect either remember. This k&n seems to keep better trims than any other intake on a stock tune. Only a couple intakes have actually thrown a cel, I'm not here to name call though.

 

I had my Hahn for 1800 miles with the GMS1 tune and never had one issue, except boost leak, which is a different story. The Hahn is great for midrange power, but that's about it, plus it does attract a crowd turning their heads. But, I ran it for a good while w/o CEL. Hahn was one of the most stable intakes w/o a tune required at the time and I still love it. Now AEM and K&N are caught up in the market, and you got the other company in TX doing their project testing now with Vararam. It all depends what is more important to you sound, warranty, tune, or no tune. Best intakes right now in the market is the Hahn, AEM, and K&N.

 

I also have the Hahn intake with stage 1 and have no problems. Great intake and product. I just wish that when I order their stuff they don't take over a month to ship because of "manufacturing delays".
