B6 S4 Power Gain From Chip

[wakzak33]

Hey guys. Have had a non res exhaust for a few years now. Went to waterfest yesterday and decided to get the ECU upgrade from APR as well as the intake. I haven't installed the intake yet, but I did notice more power in the later RPMs of my gears. I definetly notice a difference. Not crazy amounts but enough to make me feel it. How do you think it will be after the intake?

There is a very good chance the intake will hurt performance....do a search.

You may also want to move this to the S4 section...but then again you may not want to because you went with a APR tune.....

Cheers,

Has anyone ever proven that intakes rob us of power?
(dyno, quarter mile times, intake temp/flow).

in before APR chip bashing

I guess JHM doesn't go to these and have their own kiosk. They would probably make a lot of money if they did seeing as APR is able to sell their tune to unsuspecting 4.2 S4 owners :)

It's not that APR's tune is bad, it's just that JHM's is providing better results from what we see on these boards.

Yes. I personally have logged the stock air box vs the "cold"(hot) air intake, and found the difference to be marginal at best. The performance increase is next to nonexistant and infact will only cause more issues as the engine gets up to temp, since the air in the bay only does the same thing.

The vac effect of the stock airbox pulls in outside air more than a CAI ever would.

It's been done numerous times. There's been a sticky on it for literally years now, yet noone reads anymore so what can you do.

Yep, and that's why people are still buying "cold" air intakes and "chips"

[VR6 Beast]

i went to the Apr booth at waterfest to talk about their chip and he came to me and said it only gives 14hp and said not to do it! he was a great salesman!

[BlueSteW8]

Actually, yes, people do read!
That is why I have done what I have done to my car - JHM spacers, 2.5" Catless DPs into 2.5" full catback with x-pipe, LW rotors.
People have posted good information on gains from various modifications.
I have read through what information there is on intakes - including the "flapper" mod that pipes in hot air from the oil cooler.
That being said, just because brand x doesn't work doesn't mean brand y doesn't either?
APR/ REVO/GIAC tunes aren't good, so all "chips" must be bad including JHM?

Actual data results speak for themselves

Don't publicly post that, he'll get fired and the world will lose an honest sales guy and there are already so few!

Hot air is less dense, so how can that do anything other than produce less power?

That being said, just because brand x doesn't work doesn't mean brand y doesn't either?

Neither brand x nor brand y can break physics though.

Chip gains on any NA engine are pretty rubbish on a bhp per $ rating, whoever does the retuning.

Data results...like a pretty dyno? Get to a track, let's see you support APR and your choice. I'm not being a dick I just want to see someone step up and run a 12 sec 1/4 mile time NA on any tune other than a JHM tune.

My post wasn't directed at you specifically, more so the majority of other people in this section that post the same repetitive questions without doing any of their own research to see if it had been covered already. There's a ton of info on this site. I know because I've spent a lot of time reading it. My gf has a b7 a4 and when I have a problem with that car, I go straight to the a4 section and search. I can typically find a solution to the problem within minutes.

Sounds like you're off to a good start with the mods.

He's not the OP... I would also love to see another company step up and offer some real proof that their tune works well.

Shit, my statement still stands, but why is this guy sticking up for APR and his comment about if all tunes suck, so does JHMs...doesn't make sense. I have great supporting mods, so I'm not gonna say the power my car makes is all tune, but to run consistent 12s is pretty decent proof in my opinion. You can't argue about dyno queens when JHM tuned cars dominate in the real world.

[ttuned audi]

If jhm wasn't around, (IF) then would apr be the route to go? Don't make the guy feel dumb.
Or would giac or unitronic be the chip to go with?

"If" the Internet didnt exist, would you still start pointless threads?

Show me a B6/B7 S4 that isnt JHM tuned and is fast, there isn't one so let's put the whose tune is better talk to rest. I will honestly say that if it wasn't for JHM I would have sold this car a while ago.

[UnstableOS]

C'mon, the JHM tune is great and any of us that have used it knows that. However, the APR tune is not a bad tune, just not as "flexible" as the JHM setup. APR has been providing great products for the Audi scene for a long time and I would have no regrets with their tune unless I was really getting into a larger build.

Enjoy your new ECU tune OP and don't let the forum critics make you feel like you got robbed.

(IF) that were the case... leave it stock

Not exactly worth the money IMHO.

Simply because a company makes a good product for one type of Audi (i.e. easy to boost up an existing forced induced platform) doesn't mean they're automatically good for another. That's a flawed assumption but one that is often made.

[vdubjetta02]

APR's website use to advertise the tune for the 4.2L S4 was +0 HP gains...... It actually used to say +0 on the website



From APR's website - 91 octane gives you ZERO power, 93 gives you +12 to the motor.....

Actually I'm NOT standing up for anyone, just questioning the logic (or lack there of).
If you read my signature, you might note that I have several JHM products on my car.
And that I hope to get the tune soon as well.
From reading the forum, I decided not to go with APRs tune, though there is a local dealer.

All intakes are not exactly the same either - I saw short falls in several designs, with APRs being the better of the bunch.
That being said, there were improvements to be made - as there are with many products on the market.

Semper Fi, Bro

So basically I got my intake in. I messed with my MAF (mass airflow sensor) while doing it. Not only did my check engine light come on. but my ESP light came on too? Strange? So now when I put my car in neutral coming to a stop (if i dont use engine compression) when my idle drops sometimes its so drastic that my car stalls. So far, not loving the intake lol pretty dumb investment. doesnt even look that cool :(

[Apat]

Recheck your MAF plug. If its connected you probably need a new MAF. ESP light will trip when the MAF goes out.

[EUROSWAGR]

make sure your MAF is facing the correct way, I've seen put them in backwards and if the air is flowing from the backside you will have problems.
