    • OE Tuning Audi S5 custom dyno tune results - +15 whp

      This car was tuned in Massachussets by OE Tuning dealer Brentuning. The car is completely stock on 93 octane fuel. Solid gains through the curve of 15 wheel horsepower and 18 wheel torque are seen. This dyno is a dynapack, which is a hub dyno. There is a visible torque dip at 5000 rpm which we are not sure what to attribute to and will try to get further details on.

        I was the one doing this S5. This was the owner's response:

        Tune is great, car feels awesome. I definitely notice the throttle response improvement and I can feel the torque gains...
        The exhaust sounds significantly louder and cleaner (which I'm very happy about)


        Look up any S5 dyno graph, they all have that dip - stock / tuned / race gas doesn't matter. Although strange - It's part of the natural powerband. Much like the vanos change over on piggybacked 335i's.

        FastGTI - I thought I schooled you on the dynapack thoroughly in the last thread, you simply do not care to understand and that's fine with me.

        Its a great gain from just a tune, but i still always SMH at Audi for lacking a better motor in that gorgeous of a car

        We both have our own opinions and experiences.It still is a nice percentage gain over baseline tune and that's where it counts.

        So it's likely a stock cam issue?

        If it's anything like when I tuned my B6 S4, the dip is likely from the manifold runner length changeover.

        Just to add a bit to this thread. I know a lot of the forced induction crowd feels that getting a tune done to an N/A engine is a waste of time, but nothing could be farther from the truth IMO.

        By way of background, I'm familiar with the virtues of a F/I engine (I had 6 different turbo setups on my old B5 Passat ranging from the stock K03 right to a Comp turbo 5556), so it's no bias on my part.

        However, what a lot of people don't get is that things like remapping the throttle response, although it doesn't net any additional power per-se, makes an appreciable difference in day to day driving.

        I mean, the entire reason that you get an N/A engine is to have torque WHEN you want it and HOW MUCH you want.

        Unfortunately, in the name of emissions and fuel economy, throttle response and the according torque delivery is numbed out.

        It's quite easy to see why, as acceleration requests require disproportionally large amounts of fuel as crisp tip-in requires a period of enrichment to keep the fuel from puddling on the manifold walls. So in order to post better fuel economy numbers, there is a delay built into the engine management calibration.

        I find it annoying beyond belief when I see a brief opening in traffic and when I go to hit the throttle the car goes "oh.... you're sure you wanna do that?.... really...? well, let me get back to you.... OK, I'll do it, but you'll have to put the pedal to the floor otherwise I can't authorize that torque request... LAME!!!!). So at that point one of two things happens 1) The opening dissapears and I'm stick behind some asshat in a Kia driving 10 Km/hr under the speed limit or 2) the car winds up, jackrabbits ahead and then I have to jam on the brakes as I dive into the spot.

        As well, it should be noted that transient responses and power don't show up on any of the 'accepted' measures of performance such as a dyno, or 1/4 mile. However, they DO show up on a 'butt dyno' graph, which (at least to me) is the only dyno that I give a damn about when it comes to MY car.

        Having written my own tuning file for my B6 S4, I can say that it completely transforms how the car responds. While I have quite a few mods on my car (catless downpipes, catback exhaust, re-engineered intake manifold (my own job), shaved throttle body shaft, my own design of intake and W/M injection) I absolutely LOVE how my car now does EXACTLY what I want EXACTLY when I want it. To put it into words, it feels like it's gone from a 4400 lb blunt instrument to a 4400 lb scalpel *thumb-up*

        Anyway, just wanted to weigh in on the benefits of a N/A tune.

        PS: oh yeah, and the OP stated, they do make extra power above and beyond the stock levels as an added bonus lol Click here to enlarge

        Don't consider this a solely forced induction crowd. Many of us have NA backgrounds and we're about boosting performance in general for your car not just forced induction.

        NA tunes make a big difference!
