wait so HFC/test pipes and the headers are seperate?

I thought that the headers replaced both of them.

Long Tube Headers replace the stock manifold and the cats (or HFC, or Test Pipes)

Short Headers replace the stock manifold only.

I see.

so lets say I go intake, header, exhaust. would I need a retune?

It would certainly be prudent, yes.

Does anyone have a dyno chart of their car that has or currently is running all 4 mods? or all 3 mods to include long tube headers?

I'm curious to see the a/f ratios...

And you read me at the same point too and I dont have a tune and only had the CBE and K&Ns drop ins.

Wow I just learned a lot by reading up on this thread. I have a question then, since I will be running FI CBE w/test pipes and might do a K&N Drop in would I need a retune for that as well? I plan on most likely getting a tune anyway but I was just curious if this would also present a case to retune seeing im not actually switching the CAI.

Just dyno your car after you get all your mods in. As part of the dynoing process, they measure your AFR. (Not all places do it automatically, so you might have to ask for it.) If your AFR is in the acceptable range, then you're good to go. If it's out of whack, then you know you need a tune. There's no sense in guessing on whether or not you'll need a tune when you can actually go get your AFR measured and find out for sure. It's like trying to figure out if you need blood pressure medication without getting your BP reading checked first.

Good analogy about the blood pressure medication!

problem here is.

finding a company that does these things.

chiptuning is considered a illegal carmod so there are barely any companies that do them and god knows who is actually good

Im not sure if this means I am running lean but again when I did the K&N drop ins and the CBE my tail pipes went from having black junk on them(before the mods), to not having any black junk on them after the mods. But something changed. Im getting my Cobb today so I will do a AF reading before and after to see the changes and where Im at when at higher rpms then idle before I put the new map in. I think I went leaner than I was but thats not to say that Im too lean to hurt anything, Im sure the tune will get me some extra gains.

The maps that come with the Cobb from AA are really your best bang for the buck, for $100 you get a tune that is 90% perfect for your car. Other companies have been doing this for years, had it done on my turbo car. You can spend the big bucks for the dyno tune and probably only get an extra 5 hp out of it but you will have spent alot of money. So for you buying the Cobb and getting the tune that, no one will know that you have it and they cant say its illegal if they dont know you have it.

:iagree: VK, another option would be to get an e-tune from UpRev. You buy their software, install it onto your laptop, hook it up to your ECU via the OBDII port with the cable that they provide and take a data log. You send the log to them, they make adjustments based on that log and send you your tuned ROM file back to you, which you then upload back into your ECU via your laptop. Same principle with Cobb AP (except you use their standalone AP device rather than your own laptop). You are not SOL on this.

Wow I didn't know you could do that? Record my own data, send the logs and upload the tune MYSELF? I got so used to paying $600+ for my german cars for some goon to sit in my driver seat for 5 minutes to flash my ECU.

How much does this system from Uprev cost? Im assuming it's got to be in the $1k range?

no I dont think so, AA does it too and I think they told me like $350, you keep recording your info, send it to them, they adjust, send it back, you record info, send it in, etc... till its all right. I dont know what UpRev charges.

UpRev - Engine Management <-- Go to their website. You would want to get Osiris Standard ($500).

You have to buy the AP first though, don't you? And that itself is what? $500?

I have the Gen 3's, stillen cbe and berk hfc and i just recently threw a CEL for to lean - p0171.

I have created a post detailing my situation, any feedback is welcomed!

didnt you order that Cobb AP?

interesting. is it quite easy to do all this stuff. hell I don't even know where the ECU port is :roflpuke2:

It's under your dash, directly behind the steering wheel. So like if you're sitting in the driver's seat, reach forward under and behind the steering wheel. Kinda like when doing a reacharound.

under the steering wheel, trapezoid shaped female port.

Nope, i have yet to decide how i am going to tune. I am only an hour or 2 drive to the Austin uprev site, and i think that's their home base. I may just drive up there this weekend and get her tuned and dynod.

true but its a scanner, code eraser, logger, and tuner w/software and a monitor. And when you start modding cars a monitor, scanner, eraser is a great thing to have.

Plus when new tunes come out if Cobb ever does it, they are free to download and load to the car.

Aslo I got the scanner and the tune for 495. And I downloaded the Cobb valet and no start tunes for free that can now be loaded onto the scanner and then the car.

Cobb is moving their HQ to Austin, they also have a facility in Plano, you can do all the same things with their software that you can do with the uprev, and you'll have a standalone unit with built in memory that can log up to 10 hours instead of lugging your laptop with you everywhere to datalog. It has WAAAY more features.

Right, I know all that. I just didn't want the guy to accidentally get the impression that he could get the actual AP + all the custom tunes for $350 is all. Because then he'd be in for nasty surprise.

thats cool, it is a good deal tho.

Also keep in mind, that with that little standalone unit, it has maps for valet mode and anti theft as well as your custom maps, i'd hate to have to bring my laptop with me everywhere I go just so I can access a map.

I thought Osiris recorded, data logged, etc. for 500 then you pay for your dyno tune if you want to?
So basically Cobb and Uprev offer the same feature(s) just one puts it in a nice little device while the other runs on anything.

precisely!

I don't think you understand how UpRev works. You can load up to 5 maps with UpRev, and you switch between them via your cruise control button. I have valet and anti-theft maps as well, but I don't have to plug in some device to switch to them. There's no need for a laptop as UpRev's ROM has slots for 5 different maps, at they're always at your fingertips, literally.

If you go to UpRev's site and read up on Osiris, it does all that plus it includes 3 custom e-Tunes.

I thought you were being a little sacastic in that post.

Does anyone have the Osiris here? And did they get good gains?

But this would be a problem, I actively use my cruise control :)

It does not remove cruise control, it just uses it in a way to allow you to switch between maps, cruise control function(s) still remain.

I will be getting it when I get my tune next month (after LTH), will post a review plus some pictures of the software, etc.

It doesn't interfere with normal cruise control usage. To switch between maps. you hold down the toggle in the coast/set position, then while keeping the toggle held down, you tap the cancel button the number of times corresponding to the map you want to load. So for instance, I have my anti-theft in slot 3, so I'd tap the cancel button 3 times to load it. The only way I could see this interfering with anything is if you were trying to switch maps while you were actually in motion with the CC on. But you're not supposed to switch maps while in motion anyway.

Now what I need since I dont have the Nav is a touch screen that I can hook my cobb to and see and do all my stuff right there.

How was I being sarcastic? Care to elaborate?

It just kinda read that way I guess. Atleast to me. Not mad, it was kinda funny really. I guess I just read between the words.

Actually it was Dreamers comments I was reading not yours. Oppps.

Are you gonna dyno tune, Dreamer?
