dont you also have genesis coupe 19's????... or was that a different guy
riceR's build
18
There isn't too much detail as most are pretty much self explanatory. I'll start from earliest mod to latest mod.
Stock
Apexcone HIDs
35watts with 4500k bulbs. ddmtuning.com <-- best place to get cheap HIDs.
Custom CAI
It's essentially a 3" eBay intercooler kit that I hacked up. I chose a cheap K&N filter (RU-5111). Also used the Spectre 8711 for the breather hookup.
Pipes
H&R Sport Springs
Lowers 1.4" in the front and 1.3" in the back. About 1/2" of wheel gap up front and 3/4" gap for the rear. This was with the stock wheel/tire combo 215/55/17.
Front
Rear
Road Race Motorsports Next Stage Power Pro (NSPP)
Alters the signal for the MAP. It was initially developed for the Gen Coupe, but their ECU reworked itself around that. The Sonata ECU doesn't seem that "smart" lol. Yields roughly 5 hp and 10 ft/lbs... I'll do a real dyno once I get the SFR flash. I used PCMSCAN to get the 1/4 mile and dyno.
No NSPP
w/ NSPP
Front strut bar
A 1g Eclipse strut bar. The holes need to be enlarged for it to fit correctly. But otherwise a cheap mod. Got it for $18 off eBay.
clears the intake manifold
Custom CBE
2.5" mandrel bent. 2x Borla 40659 for the mufflers. A magnaflow 10436 for the resonator and a MagnaFlow 10768 for the Y-Pipe. 2x Borla 20155 for the tips. Also got a test pipe made for the 3rd cat delete. Gives a nice growl to the Sonata, but not too annoyingly loud.
Genesis Coupe wheels
Fronts: 19x8 +35
Rears: 19x8.5 +35
Sunny SN3800 235/35 all around.
Got the rear fenders rolled so it won't rub when there is weight in the back.

ahhh okay, thats more like it 
Its been about 2 months since I got the SFR flash. MPG has gone up 1-2 even as I drive the car harder. I've noticed it doesn't take much to squeal the Conti DWS. The pedal is more sensitive. Rev limiter is bumped up, and the speed limiter should also be gone... although I'm a bit more unwilling to see if it is. Car feels better overall.
Dyno is in the works... we'll see if I can save some money for that. Otherwise maybe a few 1/4 mile runs.

It was around 220hp... although I'm not sure how accurate it is. I couldn't get the 1/4 mile in b/c a car turned onto the road and I slowed down just before hitting 60... I should have just kept it going beyond just to get the 0-60 but I didn't get a chance to do it again. It surprised me because I spun the 19s all through 1st gear, and those are much heavier than the stock 17s.
This Friday I have a possible dyno session. The guy needs to get back from SEMA in Vegas first, so we'll see.
edit: I was able to roughly calculate the 0-60 from the logs I had... about 7 secs with wheel spin throughout 1st gear. Need sticky tires.

Looking forward to the dyno results.It was around 220hp... although I'm not sure how accurate it is. I couldn't get the 1/4 mile in b/c a car turned onto the road

Got the dyno done. The ambient temp in the dyno was about 75F. 1st run (red) was with the stock ecu in 3rd gear. 2nd run was with stock ecu again but in 4th gear. It got 199hp that run, but the guy didn't save it as I only bought 3 pulls - come on man! He also said that 4th was too fast as he said it was close to 150mph. I also noticed that it smelled a sort of burning smell after that 4th gear run... so I told the guy to just run the rest in 3rd and it smelled normal again... So the last 2 pulls (blue/green) are with the flashed ecu.
A few things I noticed with the flashed ecu:
Final thoughts: My assumptions about the ecu needing time to adjust seems to be true... The second run with the flashed ecu ran much better. @ ~2.2k rpm +20hp and +55 tq vs stock. That's why I'm able to spin those 19s! LOL. As expected, low end is way better, and top end is a wee bit better +4hp and +3tq. Maybe if I go back, I might get better numbers once the ecu is settled in, especially at the top end... but I don't live in the top end much, so low end is much better for me I'm pretty satisfied... now its time to find some sticky tires

- The car didn't seem to run correctly the first pull
- Thats alot of low end torque!
- ecu seemed to adjust better as it went on
- Really lean ~ 13... stock was around 12

Went to BTRcc's tuning day in IL and got a custom tune on July 30, 2012.
The baseline with the stock ecu was 186 hp. BTRcc's tuner was able to squeeze out 217 hp from it. Roughly a 30 hp increase.
My thoughts: WOW! The gas pedal was very very responsive, just as if it was drive by cable. The car felt completely transformed. Feels much faster than stock and the SFR flash. On my drive back to MN I noticed that I was consuming much more fuel than usual going 70 mph. So I turned on my torque app and turns out the speedometer is off by almost 5 mph. So I was really going 75 mph. Weird thing is that whenever I was under 30 mph, the speedometer was correct. After 30 mph, it started gradually getting a bit off, until it was 5 mph over while reading 70 mph. I didn't test anything faster than that. This was with the stock wheel/tire combo (215/55/17). Due to the speedometer being inaccurate, the mileage is also off by roughly 10%. So after calculating my mileage, the fuel consumption actually went down. I gained roughly 1-3 mpg. With an average speed of 70 mph, my average fuel economy is about 31~32 mpg. I usually got 29~30 mpg before. Again, no word from BTRcc about the speedometer issue. Although I switched to my summer wheel/tire combo (235/35/19) which is a bit shorter than the stock setup, and the speedometer was off by roughly 2 mph. So that helped a bit. Other than the speedometer issue, the car has performed flawlessly. Tried to get some 0-60, 1/4 mile times, but 1st gear was useless as the tires just spun like crazy.
Finial thoughts: Custom tune is worth it! If you can, get it. $600 well spent.
