Actually yes a dealership DOES have to prove that a modification was the direct cause of a failure on a car before denying a warranty claim. Most people just won't challenge it. And those that do often end up winning the battle with the dealership.

I ran the stock tune for the first 1200 miles on the car. Cobb stage 1 for another 6k. And have now had Tune + for 16k. Gas mileage has stayed the same across the board.

I'm curious to know what you learn as well. Because when I bought my car the very first tank from the dealer was on 87 octane. I ran it about 150 miles then I did a couple of tests with the track app. Did a 0-60 and a 1/4 mile run. 0-60 was 6.0 seconds and the 1/4 mile was 14.4 at 96mph (now I...

Not sure about the aerodynamic drag. But I do know my gas mileage since removing the shutters is exactly the same as when I had them. Hopefully though somebody can answer your initial question.

If it helps every record holding s550 does not have the active shutters.

I removed mine. They did not affect anything performance or economy wise. The car has been the exact same, so to me they really are useless. That said, if you wish to keep them you would need to use a stock replacement intercooler like a cobb, or the map one. Ones like Full Race, Level's...

I figure any tune needs to go through a drive cycle or 2. My car felt like a whole different animal 2 weeks after adam finished tuning it vs the initial runs right after his final calibration.

What fuel was this on?

As already mentioned Paul@PKAUTODESIGN will be able to assist you with anything and let you know what can and cannot be done with these cars. Him owning an s550 really helps.

I wish I had good tires. I have a 4.7 0-60 on my stock all season 235 goodyears. Can only imagine what I would do on a good 275 summer tire or even a radial.

I'm a cobb accessport owner so I first and foremost would recommend that tuning device, as I believe it has the most features for the price. That said my 100% complete Unbias opinion is to look into both the Cobb Accessport and have Tune+ do a custom tune or the NGauge available from Lund...

Am I to assume that if a wheel does not require it that is what you consider a hubcentric design??

Ok that definitely helps. So these are something I will have to order no matter the wheels I get for my car.

Well they sold quickly before I got a chance at em, which is not a surprise given the price they were listed for. But while I am here I can now take an opportunity to learn. Please explain what you mean by Centerbore and what a hubring is and what it's function is. I'm hoping it's not a spacer...

Would anyone be able to tell me if AVID 1 AV20'S in an 18x9.5 +22 offset would fit our cars? I have a base ecoboost. Curious cause there is a set in the correct lug pattern for sale for DIRT cheap and I might pick them up. Here's what the wheel looks like for reference.

I'm quite curious how the RF1 in red would look on these cars. Especially if able to get a concave off set up up front similar to the rear.

This makes me a very happy person. I believe it was y'all who posted up that one of the weak points at high hp in these motors is that the block flexes, thus the brace that you design really makes a difference in reliability. So when I saw your 600hp motor and the brace I knew myself that's the...

Would you consider your race series a streetable motor that could be driven daily?

I'll tell ya this I'm not a fanboy of anyone. I went with my choice because I wanted someone who pro tuned on Cobb software. I did not want any other tuning device than an accessport for this car because of all the features it has. At the time Adam was the one who had the most experience pro...

You compare tunes all the time (and have done so in this thread). And I'll put it to you like this. The mileage is gonna be relatively the same across the board regardless of the tune on normal pump fuel. So your comparison really is rather pointless. I've ran 3 different tunes on my car (cobb...
