Do not get an intake unless you're custom tuning the car!
Ok, since I have both a Tech2 and the laptop connected GM Can controller as well as HPT, let me dispel some thought processes for the tune vs untuned vs intake crowd.
First of all, there is no tune I cannot find using tools available to any GM tech, you cannot hide it, you cannot reflash go for a drive and all is well, you cannot swap ECUs you cannot disconnect the battery and short the terminals.
Here is why. First and foremost I can reference the current software against both GM factory release for the car and any updates. Second I can see every ECM flash event through the BCM, because the BCM is flashed to the car I can look up every change in the software. You cannot HIDE a tune, it is not possible to hide the tune simply put by updating the ECM you are changing the software and thus it is recorded to the BCM, a good tech will check to make sure it is stock.
Next HPT cannot log KOEO trip events(OBDII Drive Cycle Events), but the ECM will log this. It is a comparative between drive cycles that some DTCs are dependent on. For instance Catalyst efficiency, HO2S efficiency, even misfires and evap system codes. If you bring your car in and the dealer uses a tech2 your mostly in the clear they cannot see anything except the freeze frame for whatever set code and the history if the code was set more than once. HOWEVER the newer laptop and CANbus can basically watchdog for mods, like intakes. I can tell if you had an intake on it 500 miles ago even if you reflashed your tune.
Basically what I am saying is you are paying to play guys, There isn't much case for aftermarket charge piping, or cat back exhaust, neither mod could be fingered in most warranty situations. GM doesn't have money to assume everything coming into the shop is warranty related. They'll crack down harder because the shop rate for warranty is less per hour AND the warranty labor is shorter than standard.
What comes into my shop is all the stuff warranty doesn't cover. And most of the time it's expensive.
Wang, good thread.

Thanks Army Greywolf. Most people have no idea how much more cars are becoming computerized. Me? I love it. I run large scale IT projects. I can wrench on cars, but I'm better at gathering data, analyzing it, and improving reliability and efficiency. Well, that's what I do pretty much all day long at work, but now it can apply to cars. Get a data logger, log, and perform post mortem. Collaborate with peers, lather, rinse, and repeat.
I'm not surprised that most techs cannot find tunes. Most aren't familiar with the internal workings of the ECU. Honestly, they don't need to be 99.999% of the time. People have no idea what they're talking about when they say Trifecta has a tune that's undetectable. Maybe to a totally newbie tech. Dump the data, run an md5sum. It's not possible for Trifecta's to match a stock or GMS1 tune. Sounds like the GM tools are catching up.

OK im not reading all of that but you DO NOT need a tune if you get an intake, yes it'll **** you up if you have the LSJ but because youre a turbo the more free breathing it is the better it runs, ive had one for a while now with the GMS1 and everything is fine
And im not trying to start an arguement but ive been around plenty of ppl where theyve just had intakes and not a tune and everything has been completely fine with there car. Like STI's and Evo's.
I have the Injen MR Technology Intake the MAF is inthe same spot and everything has been fine. Car runs like a ******* beast. Beats Evo's and stock twin turbo supra (not to brag), and all i have is the GMS1 like i said. I guess it depends on how you work your car.
When i had my LSJ i did an intake and completely fucked up my engine but i believe cause it got wet one day and got the MAF dirty since it was down in the fender. Idk not trying t ostart a war cause i really dont want to. lol. just wanted to share my opinion

NORTHVIBE SAID: "Saying an intake will blow up this car and is bad for it is miss information as well. My "nonsense" was saying this is a horrible way to go about informing users. Where is wangspeeds facts on intakes blowing up engines? My points are, stock tune knocks like a ****. k&n datalogged by some has kept decent trims, so how is that worse than stock or stage1? Some people dont want or need a custom tune, but telling them they HAVE to? wtf. I see both sides of having a custom tune and not, you guys only see 1 side, having a custom one.
Isnt there dyno's of stage 1 ppl with intakes getting more power? Just because a custom tune net's you more doesnt mean bolt ons are a waste.'
this is back on page 4 if you wanna find it
but he is absolutely right, you actually acquire more power if you have GMS1 installed with an itake you get more power, idk how but ive seen dyno sheets on here, look back in the basic info threads youre bound to find one, i have about 320 HP, and go figure. I guess the guys at GM know how to tune a car
Bro if you have the LSJ you should be fine
if you have LNF get the catback with out cats, MORE air going to the turbo, thats what you need

THe LSJ is tricky because it is belt driven, any air flow changes you might have to get a tune, cause the car is used to getting a certain amount of air flow. With the LNF, if the car is getting more air its no rejecting it because it wants it.

I also had my car serviced for a problem with a cam seal as well as the brakes and some other things that weren't right, and because they knew me and know I work on cars, they checked everything before they touched my car under warranty. They also verified my car was untouched.

LOL...That has absolutely nothing to do with anything we are talking about. A turbo car doesn't reject the air is LOL... If you change the diameter of the pipe, the location of the MAF etc.. you are changing the way the VCM interprets the airflow reading and the will skew the MAF's. This is simple stuff...

im officially backing out of this one cause i am too old for flame wars on the internet, peace, i do not wanna make people cry and hate me so have a good day everybody, ill leave by saying dont always believe what people tell you
BTW, look here http://www.stealth316.com/misc/obdii_fuel_trim.pdf
ill copy and paste a good part,
"Let's look at some conditions that will set adaptations faults and there causes.
Intake air leaks
Incorrect Fuel Pressure
Injector valve defective or coked
Engine Temperature Sensor defective
EGR valve defective
Secondary air leak
Fuel evaporation control system defective or leaking.
Air Mass Meter defective
Vacuum leaks
Oxygen sensor aging (slow response)
Clogged or damaged catalytic converter
Contaminated fuel
Fuel tank ran empty
Combustion altered by a mechanical failure (Spark plugs, compression, intake/exhaust valves, ...etc.)"
it says nothing about changing intakes....

Okay, from my understanding tuning for an intake is a global change in the ECU right? From what Ive been explained the MAF tables are global and not tune dependent. So if someone has a dual tune, logs the car and has the tuner tune for the intake, it should affect both tunes correct? Like in my case I have GMS1 and then a Trifecta 23psi selectable tune. So if I was tuned for my intake logging while on the Trifecta tune, it should also affect the GMS1 side of things too?

Another person that doesn't have the facts that pertain to THIS car yet knows it all....
You are posting data from a Dodge Stealth site lol. Then you are saying what can and can't work yet you don't actually know (like the rest of the people arguing) because you aren't logging THIS car with intakes to see the actual changes. Your arguement is based on another site, another car and nothing to do with THIS car. That list doesn't show how the car will go into a limp mode when the MAF change is greater then 20%, OR how this car knocks excessively when the fuel trims are way out of wack.
If you saw how this car reacts with a tuned intake vs a non-tuned you would see what is happening. This car is extremely sensitive when it comes to the MAF tuning, just that alone will make the car clear up it's KR thru the midrange.

What's retarted and a waste of money is throwing expensive aftermarket parts on your car, then not tuning it for them, so that your car actually runs worse than it did before you spent a bunch of money.
What's retarted is putting a part on your car that makes it run unreliably, just so you can hear the sound of a BPV opening.

Some of you are way off base here. Let me make this very clear. Most of you have very little if any tuning experience so your arguements are baseless. I see some comparing a Dodge to a Chevy. That is not a valid comparision at all especially given the fact that most Dodge cars and trucks are speed density (SD) tuned. For those who do not know what SD tuned means it means they have no MAF sensor to measure airflow. They base all their fuel calculations ( calculated cylinder airmass) off RPM, load, and MAP. Because there is no MAF sensor to skew you could put a piece of 6" PVC pipe on there with no filter and the car would run just fine. Try that with a MAF tuned car and see what happens.

That's a lot of what I was getting at when I posted.
There is fueling via MAP vs RPM then theres Alpha N which is RPM vs TPS, then theres MAF, etc... I've seen too much mis information in here to even bother with most of it. MAF driven cars are sensitive... this is also why you have to be careful running an atmospheric dump BOV as well.. But that's a whole different topic.

Okay I had pm'd term2 a while ago and never got a response. My thought was, everyone with data logging abilities, log their car stock, and then install X intake and data log, and we have a thread sticky for us where we can post the environment details (weather etc) and the logs to show what is going on per intake, per location. THEN everyone can see actual logs, from more than 2 people and actually data instead of just what is "said" on the forum.
Exactly.
