Jordster, there are some big names in this thread, they do know what they are talking about. Alot of intakes due mess with the car. some not as much as others. The K&N at the moment seems to affect it the very least so far. What they are saying is it still affects the car. Not by how much or how little. In their book, "Fuel trims are skewed, intake is bad." Must blow away warranty.

I agree a tune is needed to gain any power but this thread has gone so farr away from what it was meant for. A guy posted this thread stating intakes must be tuned. We are here stating some intakes do work fine. Then they are stating they still need to be tuned cause they skew fuel trims. Then we are stating, the stock airbox skews fuel trim worse than this intake?

I will "data log" stock airbox, and the intake... I just need a data logger... or program to data log.

Im not planning on doing to go "In yo FACE" Im only doing it for scientific purposes.

 

BYT im going to PM you and chat with u off this topic so no bullshit comes up

 

I suggested it, why would I knock it? why are you trying to keep information hidden? I dont mean to offend you, but how can people take someone seriously when they wont show data, just say their findings or opinions.

 

when you say 10-20% is this a range for stft's moving? or you saying the ltfts are between 10-20% off.

I will tell you my numbers right now on my car. ltfts are between -3.9 and -5.4.

at WOT my stft's are -1.5 to +1.5.

 

It's not that they are slightly off from the norm, we are talking big changes here. 1-2% would be totally acceptable and run fine. 10-20% (depending on the intake) is significant and SHOULD be tuned for. Can you run without it, sure. Is that a good idea, NO, not in our opinion.

The K&N does seems to be the least offensive to the trims, that doesn't put it in the acceptable range tho. Will the car die from it, prolly not.

 

I think it's safe to say these cars are damn finicky when it comes to intake mods and if you choose to go that route it pays to monitor what's going on. I don't have the capability to data log at this point so the drop-in and AEM coupler are currently shelved.
Along these lines, I noticed in another thread (LNF section?) Gettingausernamesucks, who I believe is a GM engineer, posted his setup: GMS1/catless dp/removed snorkel-K&N drop-in-3 in. coupler. He added that his car runs flawlessly and pulls 12's with sticky tires. One would assume he has logging capabilities but who knows-he also didn't mention any airflow straighteners.
Unless he's running on the ragged edge this would seem to go against Terminators findings/sound advice. Thoughts?



(Similar to original ZZP mod-obviously they're not GMS1)

 

dashhawk
interceptors
hpt
I assume trifecta via laptop as well
dashdaq
more?

 

Because why do I need to spend my time to prove to the handfull of people that refuse to listen? Not to mention, you didnt shell out the $550 for the device yet you have no problem telling me what I should be doing with it. I have nothing to hide, hence the reason we are posting what we found trying to inform people.

You have the stuff yourself, you are questioning this and can't believe it... Go find out

 

well I know on letting off on the gas at partial throttle lets say.... from 40% to 20% throttle, I see a stft spike for about 2 seconds or less of about -16.0 to -18.0 but then goes right back to -2.0 to -4.0

I saw the same thing with the stock airbox.

 

ok so apparently the whole PM thing wont work...BYT i have my car tuned for the K&N drop in right now and i want to put the Dejon SRI on my car...how bad do you honestly think it will be without retuning it??

 

alright I have a interceptor.. I guess I gotta read the manual to see how to get it "data log" and record it to a computer and graph it?

 

I would not install the SRI without a tune for it. You are already TF tuned, put on the SRI and pay Vince to update the file.

 

alright, i have been trying to get ahold of vince for a long time...its really hard to get ahold of him lol

 

He was just on vacation for 2 weeks, he is back now. I just talked to him last night

 

Your car won't "blow up" necessarily, but what's the point of installing an intake and not getting the full advantage of it? Don't be a cheapskate, if you're shelling out $200-$300 for an intake, get a tune to go with it.

 

^Or skip the intake and spend the money on a tune. The tune will be a TON more beneficial then the damn intake. And don't bring up warranty because technically you need to remove that intake to get dealer serviced as well...

 

Yeah that, most tuners give free updates anyway, or cheap at least. Then when you get an intake, just get a re-tune. It's not hard.

 

beast thanks bro i will try him again!

 

do work son!

You go clean your rooM!

I have an intake but no tune... whats the point? who cares. I like the intake, makes the car sound sportier. Why dont I have a tune? I will get when Im good and ready! I need to rice out my car alittle bit more.

 

Cant believe it? I was never a nay sayer. you keep thinking I'm like against a tune or something... So will you post a data log of your car as it stands right now?

 

I don't like knowing that my car isn't running as perfectly as it could because I decided to not spend the extra $ and get a tune to make it healthy. I don't even have an intake because of this, I don't like how ANY of them really are on the car even when tuned. To each their own though, and my own room is clean lol.

 

I knew that, I know how to record.... but I dont know how to record in a manner that I can transfer to this website! theres no data cable that plugs into a PC with software.

 

no lol. Why would I? What does that have to do with what we're talking about? And you wouldn't be able to look at it anyway since you don't have HPT

Im not saying you are against tuning, you are against NEEDING tuning for an intake. So go find out yourself by logging, you have the stuff to do it yourself and the parts to test it out with.

 

well if your not tuned now with a stock airbox, I guarantee you your car is not running to the best of its abilities.

Girl you would not survive in the cars before 2005.
