From "stay tuned" to T U N E D !!

**Klasse Act** · 09-10-2023, 08:06 PM

So THEE day has finally arrived, Sunday was changed to Tuneday

️ Great weather and earlier arrival made for a great install, plus my buddy had ZERO issues with anything, as expected

So here's a run down of what was swapped out/added to the EN today:

-N Performance intake, an OEM option in S. Korea through their dealerships. It hosts a larger intake pipe, large cylindrical K&N-type air filter that simply twists out for easy cleaning. Speaking of cleaning, it also has a window for viewing the filter for when it needs to be cleaned

-Shark Racing turbo inlet pipe. This is a larger TIP to improve air flow which has a high quality ceramic coating, VERY nice piece without a doubt

-MSD perf coils. These meet or exceed OEM specs and when asking for more performance it's a great idea to keep that spark STRONG and that what you get here, well respected name in the industry! These are nice pieces which are red capped but sadly, aren't going to be seen as the engine cover WILL BE staying on, I mean look at that ugly engine under there

-NGK colder spark plugs. These are required for the ECU tune. The OEM plugs were also NGK, another well respected name in the industry.

-Mobil 1 0w40 oil and K&N oil filter. Now my "tune up" kit had oil included in it but it's 5w40 and since we're going into fall/winter I opted for 0w. The tuner got back to me a little late and said I could've ran 0w30 for winter, no worries as it's still 0w.

-N75 ECU tune...last but certainly NOT least! I opted for Stage 1, basically "OEM+" IMO. No more stupid "octane learning", the main reason for this in all honestly! I run Shell V-power, 93 octane and this takes full advantage of the smart enthusiast who knows to run 93 octane in a perf car!!

Another great feature is how it leans out the rich tuning Hyundai does from the factory, thus giving you a smoother running engine AND better mpgs, I already saw a gain on the freeway but a true test will be coming up soon enough (yeah I'm the dork who cares about mpgs in my tuned car, sue me

)

All safety features as far as parameters stay in place here as well, these guys know what they're doing without a doubt

Now that you know a little bit about the parts, let's talk numbers. Per N75's website and surely input from customers, this tune alone makes 295 whp/310 wtq (latter IIRC) and with the addition of my N Performance intake and Shark Racing turbo inlet pipe, according to N75, I should be at 300 whp/330wtq . Well my buddy's EN w/ more miles than mine and same trans put down 277 whp and 283 whp w/ NGS, torque was 283/289 (w/NGS). Oh and btw NGS is the red button on the steering wheel (DCT cars) that puts the EN into "overboost" for 20 seconds, a feature that's been disabled w/ the Stage 1 ECU tune from N75, don't need it anymore according to them.

So onto the results aka the "butt dyno"! Well after we cycled the new ECU tune through, let it run to make sure all was good, my buddy and I took it out for a "shakedown" run, here...we...go

️

Once we had a good stretch of open road I just nailed it...20 psi held, dropping for a second to 19 psi during shifts and back to 20 psi and it absolutely pins you into the seat! I could feel the traction through the steering wheel but it was NEVER unsafe, even my buddy Hectour could feel it through the chassis over in the passenger seat, thank God my buddy Marsin swapped IN those Powerflex bushings, LOL.

While out we rolled up on a S/C'd S4, I paced him and nothing, well, until I started to turn and then he floors it right by us, guess I lost that one

From a slow roll, like 20 mph, it spins the tires but not horribly, atleast it didn't feel like it so again, the Powerflex bushes paying dividends. Btw, the 2024 EN's are supposed to have upgraded bushes, hmmm, what a concept.

Now I haven't tested launch control yet and I don't expect things to be good here, more power should just make them spin more and quite possibly "wheelhop" worse because they did just that when I tried launching it w/no aids AND NGS turned on, just spun and wheelhopped...this was yesterday

Oh well, this isn't a drag car but we shall see...once "just to see".

I will be dynoing the EN next month, same place my buddy Marsin dyno'd his EN during the spring. Soeaking of him, he's going a slightly different route with his EN

He's opted for the Stillen TruControl piggyback tune. This unit has dyno'd 50 whp/55 wtq per the dyno Stillen used. He's also opted for the Stillen cat-back, a 3" mid-pipe and 2.5" axle-back portion and their specific perf muffler. This system dyno'd 14 whp/14 wtq but that was on a stock car, not tuned and don't think combined it's going to make 64 whp/69 wtq, just doesn't work like that
