I have a 2016 sti it is completely stock and I'm finally getting the itch to get some extra hp. Wasn't sure which direction to go but Ik the ap is the number one thing to do. Not really to sure though what to do after I get an intake and exhaust. This car is pretty much my daily as of right now. Don't really put more then 25-30 miles on it a day. Jus looking for a little guidance. Appreciate it!

Well if you going to get an intake and exhaust then the car will need a tune to run the intake. A tune is not needed for a catback exhaust. Now if you decided to go for a down pipe then yes a tune is REQUIRED. Cobb does have tunes available that are free but be aware that the cobb tunes are designed for cobb parts.

Your best bet is to get the car protuned to safely extract every bit of power. Unless you go open source, the cobb accessport is REQUIRED when getting protuned. So yes cobb accessport is worth it, especially the V3 accessports.

* realize adding power will give reason to deny warranty repair. I wouldn't do it till out of warranty. What you need to learn is what you want, what you will spend, and the common configurations that get you there. After that
* Don't ask, read and learn, read and learn, read and learn. Then decide.
* If you don't trust yourself, think twice. If you still want to mod, read and learn about great shops and find one. Discuss with them, and decide with them.

I know it will def void the warranty and I did some research on it. But I wouldn't say to much. I got about 14k miles on it right now.

I found a good tuner around me in Long Island and I know some people who went there personally and there cars have been running superb for a few years now But I'm curious if I run the cob standard tune let's say jus stock 93 octane and once I start building on it a little then go to the shop n get it tuned. It shuld be ok. And if I was to get an intake I think I was leaning towards a Cobb any way so I could run there website tune

I think the Cobb AP is worth the money in the Long Run, You'll need things like a AFR gauge and this again will be good to have in the car, along with a Boost gauge. I ran PLX on my last 08 STI that was built and was great, because the tuner could tap into it while doing tuning, saving time and money. The real question in my opinion is " Is it worth just having a pro-tune on a stock car to avoid unnecessary problems with ring lands or follow the rules until after warranty? It takes roughly 120 miles to re-learn the ECU " Flashing back to stock" If you go to the dealership before then , then it'll say something to the effect of " System not ready, giving them suspicion that you've mucked with it.

Uh, yes. If you like power anyway... :)

There are lots of options for ECU tuning, Accessport is one option.

Getting your car tuned by a pro is the best thing you can do.

Finding a "real" pro is the hard part.

Finding someone who say they are a pro is easy, unfortunately.

Custom tune with open source software is roughly same cost as AP, if you are not planning to mod custom one off tune might be better otherwise yes AP is worth it

And this.

If you are looking to do things properly and get a custom tune done by a pro, the Accessport is probably the most expensive option. You'll pay usually 400-600 for a tune regardless of whether it is done through an Accessport or through opensource software. Then Accessport is another 600 on top of that.

You can run the off-the-shelf maps that come with the AP, provided you use EXACTLY the parts listed for that map. Even then, it won't be nearly as good of a tune in terms of power, drivability, and safety as a map that's made for your specific vehicle.

The AP also comes with some other neat things, like being able to switch maps on the fly and the ability to datalog and monitor certain functions. Up to you if those other things are worth it.

Looks like you don't know, because an AP definitely does not void a warranty. It does, however, mean you can possibly denied warranty claims should something happens and SoA links the failure to the AP.

With regards to the AP, I think the ability to log realtime is very useful, especially considering it's small enough to just put in the glovebox when it's not being used.

I don't really care for the OTS Maps, but the device itself presents quite a few options for people

Agreed. I also really like the valet mode map.

That being said, you can datalog quite easily with a $100 Tactrix cable and a windows laptop. So it's not the only way, just the simplest.

I'm gonna disagree with 90% of these replies. Ignore your itch. If it's your daily, assume the worst unless you got enough surplus to rebuild an engine. Just take a look at social media, 9 times out of 10 you see things like "I bought an AP and now my engine is blown".
If you are gonna mod it, find a good tuner first. Talk to them about putting them on and tuning right then and there. That way you aren't driving the car without issues.
I still don't have an AP and I'll never have one. I don't need that extra stress in my life, drive until it breaks is my philosophy. Just my 2c.

i bought an AP, installed it for a few miles and removed it.. thought id give it a second go and divorced it less than a day later.. it now sits unused in my basement office.

quite frankly, the stock tune is more fun than the OTS cobb stage 1 map.

i mostly agree with b18c5rjdm, keep it stock.. drive it until it breaks.

I wouldn't get an AP again until it's combined on the same purchase with a downpipe and a proper pro/e-tune.

Stage 0/1 tunes aren't really worth it. The intake, whether CAI/SRI, isn't worth it at all.
My OEM tune was rubbish, it leaned out under load, which is far from perfect.

If warranty is something that you want to rely on then I suppose it's fine because you can hit up Subaru if you have catastrophic engine failure.

Me, I had the car tuned to avoid any OEM deficiencies, I would rather rely on a good tune for reliability, the cost of a good tune is insurance in my books.

Point of note: If you are running on a poor OEM tune it may cause issues that don't raise there heads till your warranty is out.

IMO, and from research I have done, the OEM tune is more based around emissions rather than safety.

The first thing I usually do when I buy a new car is to get it tuned, buy a pro, on a dyno, I have never had a issue over all the years I have been doing this.

I put this down to only using the best people and equipment, too many people cheap out on something that should see the most attention.

I mostly agree with Noximus. I bought both at the same time, but didn't have time to install the DP for a while. Course I'm "old school" in a GD and things have changed a bit. But Both my OTS tunes were fine. Stage two was far better than than stock and leaned less than stock It was a huge improvement and I drove it for 75k with no issues. Would a pro tune have been better - yeah some, but there was less left on the table than I had gained. I didn't pro-tune for the same reason everyone else says you should! I didn't know who to trust and I knew it !!! When I was ready to build I traveled . . .


Yes we have seen some complaints about Cobb tunes, but we see complaints with stock tunes and protunes too . . . my impression is that they have gotten better - and I don't understand how they couldn't be, they promote more complex tuning and are making it easy to it do it . . . like hybrid maf/map (speed density) . . .
