no the CP doesnt need a tune

 

And again, we're talking about a car that is DEPENDENT upon the MAF as the car runs in closed loop. Therefor, "all you're saying is" absolutely wrong.

The MAF calibration is based on the stock airbox/filter. If you change the diameter of the intake tract, move the MAF (even the slightest bit), are allowing more air through the tract via a high flow filter, it's going to cause problems. Therefor, you need to re-calibrate the MAF in order to not only reap the benefits but to also keep fueling/KR in check.

I believe this has already been posted on the first few pages...

 

CP shouldn't affect anything so long as there aren't any leaks. Yes, if you're putting the stock intake and filter back on, disconnect the battery to let the fuel trims reset.

 

My saab is run the exact same was mass air flow relyant like your friend said already so im letting you know mine is not as wimpy.

 

so stock intake and dejon charge pipes and hks bov is ok? just aftermarket intake= aftermarket tune then?

 

cool thanks lol less work to do, back to the ugly plain stock air box i go o well just more reason to get a tune faster

 

If K&N will go as far as saying they will handle any warranty problems, they obviously have confidence in their product so I'm gonna trust them because I have the peace of mind if something goes wrong, it will be taken care of. And another note, it's a pretty big accomplishment when the intake has been out since May and I NEVER heard ONE person complain about problems with it........that says a lot right there. IMO

 

I disagree, I believe there's a lot of companies that will say anything to get you to buy there products even major corporations like microsoft saying Xbox 360 not having 3 ring death issues and don't worry. Yet there are still xbox's failing (not slim from what I understand), Windows, zune etc. K&N could be different I don't know them well enough, but for me my rough idle went away after I took off my drop in filter. This is my experience, with k&n so far.

 

True, you have a valid point and this coming from someone who is on their 3rd Xbox 360. All of which was replaced under warranty. As far as the K&N Drop-in goes, I just disconnected the negative cable and let it sit for 10 mins then hooked it back up, seem to work for the idle and sputtering. So far with the SRI, I haven't seen either.

 

no. bov's NEED a tune. That I will fully back. This is a bpv system. Adding in a bov is just going to cause some headaches. tuning will help out with that.

 

slims still fail. ya but this is a bad analogy. MS makes the product you use 100%. K&n makes a part that goes on a GM car. GM covers the car warranty, k&n covers the intake warranty. two diff things. For them to "cover" and talk to the dealer is good. Its 1 less thing to have to deal with if trying to get warranty work done. K&n seems to of put a hell of a lot more r&d into their intake than others on the market.

It will still be a fight to get warranty work done, dont get me wrong, but to have k&n say they will talk to the dealer is a help.

 

I've logged the k&n for 300 mile cruise and a couple pulls. My stft's bounce around some yes, but they do not go so dramatic to cause a engine failure. idle is 0, may go -.8 or -1.6. WOT was around -2.3 and partial throttle was where it got more bouncy around +- and letting off the gas. I'm gonna swap to stock airbox soon and log as well. I'm waiting on a new DH cable though, damn thing keeps rebooting.

 

That's good to hear, I can definitely live with those fuel trims. And I agree, it will still be a fight with warranty work however I'm from the smallest province in Canada so my dealership probly never dealt with someone who modded so since I always got my work done there, I'll have to sit down and have a chat with the service manager and show him the card that came with the intake and explain what I know about it regarding fuel trims and what not. I'll have to invest in a Dash Hawk to moniter it. Hopefully they won't give me greif over it and if they do............then f*** them, I'll buy a 5.0L Stang instead of the Camaro if they'll be dicks about an intake from the industrys leader.

 

dont bring up fuel trims Either, swap to stock for warranty issues or bring the card in, tell him you bought this intake and ask if there will be any issues BEFORE you install it. Then he wont think you put it on yet. You dont want to give them any info they dont need.....

Dashhawk is nice, used ones are cheap and they can record info, 0-60 etc and have usb port to move data to PC.

 

u guys seriously confuse the **** out of me....i get that puting an intake on your car will skew the MAF but i feel like if i put an intake on my car its gonna blow up if i take it to the track untuned....idk i guess theres so many damn diff opinions on here i dont really know who to believe, granted i believe BYT and Term2(because of there background) i am even hearing diff things from Vince....and with the BOV vince told me u dont need a tune to have it, the only thing u would need a tune for is to delete the code it might throw from the stock BPV...i want it to be fast but i keep reading more and more **** and i dont even wanna touch it now, and there is no one near me who knows how to work on these cars and ****, i have vince near me but its not like he will go to the garage with me and work on my car

 

well it is the internet, and everyone on it states their opinion as fact...you gotta do your own research and wade through the BS

 

i guess so bro, i have no way to log my car so.....looks like i need to invest in a dashhawk

 

you guys having the ring of death with the 360 need to come over to the PS3 side no ring of death there. i have had my PS3 60 gig for 4 yrs with no problems. and as far as the the intake goes just let people do what people want to do. poeple dont need poeple try to scare them or tell them to not get something or it will blow up. tuners need to stop try to get people to tune their cars. just my input. i will do what i want to do to my car and thats what everybody should do what ever they want when they want without being told something about it. if it looks good sounds good and with out having to look for problems works good then do it. remember anybody that wants to find a problem will find something to make them right even if its at the expence of other people by making them get tunes.

Video of a Cobalt SS with a K&N untuned running at the track... Did not explode and ran a 14.02@ 103.6mph. I beat the stage 2 Cobb tuned 2008 Wrx sedan.

 

I did, I'm a proud owner of the PS3 Slim, however I don't like the fact the online isn't as robust as Xbox 360. However I like the fact there's a lot less chatter and racist kids on PS3. so pros and cons.

As for your statement about do what ever you want without care, I disagree with that. Tuners may have an ulterior motive, but if they're genuinely trying to prevent me from having issues then I don't mind the early warning. How do you know I guess. Well you don't which sucks, but there's nothing wrong with running stock. For me I chose, "better safe than sorry" route.

I did get scared that it changed my entire outlook on how I'm going to mod my car. Then again people that don't understand something are usually scared of it, I'm a prime example.

Because of this thread infact I plan on just a GMS1 and Hahn DP and just styling stuff and calling it good. No intake, just GMS1 and DP.

Originally I planned on a spring 2011 Trifecta, K&N SRI, Injen CP, ZZP DP, and BOV. With plans on possible intercooler. Then I was going to get a catback, find some headers and get styling Mods. It wasn't going to stop there, I was going to keep going until I can't anymore.

So yeah I guess I got scared out of modding which sucks, but I can wait until the format grows.

 

It is not normally going to blow up. That is because the car is constantly in closed loop mode so the WB will sense the A/F and correct accordingly, unfortunately, it can correct only so fast and will sometimesover compensate or undercompensate. The car will drive better, will be faster and safer if the MAF tables are properly tuned for any intake or intake mods. Will most people's cars blow up? No but some intakes do make the car run very lean or very rich for a while.

 

^An Injen intake may very well cause damage, they are just so grossly off from the stock tables. The 1 that I tuned couldn't even accelerate to redline without feeling the car nose over really hard! Greater then 20% change in some spots

 

ya I heard that one is nasty.

Its been a while since I was "stock", does 3rd gear feel sorta hesitant? I thought it was....

 

Weird I saw logs from TOFU when he had an Injen the LTFT was -7 and the STFTs were averaging +6 to -8. Not as bad as the Hahn on my car. MY LTFT was +11 untuned with the Hahn on my car.

 

ive tuned an injen and it was about -15% through out
