If its yellow, let it mellow, if its brown, flush it down. Oh wait, wrong kind of flush

I know this is going to be hard to swallow, but unless you're getting a tuner, the factory box is your best bet with your factory tune. I have a 2010 like you and have been thru all the intake variables. I am very pleased with my SCT X4 tuner. Save your money on that other crap and just drop a K&N into your factory box, yank out the little lower snorkel, and install the 91-octane tune. Good luck

Good News. I called SCT and on the phone in my car they walked me thru re-installing my factory tune. 3 days later I passed CA smog test. It seems I was on "Demo" mode when trying to return to the factory tune, and the tuner was seeing the car used when setting up the "Demo" tune did not match the car it was currently connected to - ergo, bad marriage. Didn't need a laptop or PC to fix my problem. I'll be returning to a performance tune later today. WooHoo !

Nick. There is one possibility. A couple weeks before I went in for smog check, I set my tune back to factory - I think. I may have set it to SCT's 87-octane tune however. I say/write this because I after setting it back, I did not remember my car running that good on the "factory" tune. So what may have happened is, perhaps the smog check guy flashed an update as part of his smog checking and now my married status failed. Who knows what happens at a smog check!? My failure was due to the oxygen sensor "not ready".

I've had my SCTX4 for most of a year and I was fine paying $399 for the performance its 91-octane tune provided... Until now. I failed smog testing! I could not switch car computer back to the factory tune via the tuner, which is a big advertised selling point of the damned device! Got an error 110D5 - Married status failed. I have since googled to find many others had the same problem. Now I probably have to pay $200 (guessing) from the local Ford Dealer to load in a factory tune. So I have in effect, a $600 paper weight! I left a email/message on SCT's website on Saturday but here it is Tuesday and no reply. I loathe to see the dealer or get on the phone with SCT. My home internet is done (ghad damned HughesNet - that's another story). I'm a thrifty person and now in my sixties thought I would splurge a little and this is what I get. Be warned everyone.

Hi. I can't seem to paste in the url for this but if u go to ebay and search for "Black Ford Edge grill", you'll quickly find one for $89 shipped. Has anyone installed a "replacement" unit like this? It is not a bolt over thing so it may require drilling. I'd like to know how hard it is to install and can I put back the stock one if I need to. Thanks.

Don't waste your money on that sprint booster. Their website specifically states it will not increase horsepower. Your tuner will make your car very responsive and add horsepower. Spend that money on beer instead

Hi MikeKilo... If you're referring to me (3500cc), I have the SCT4. It came with canned tunes and I'm currently running the 91-octane canned tune. I also modded my factory air box - pulled out both snorkels, Home Depot plugs in place of intake pancake, AEM drop in dry filter. Intake sound is always present to some degree. I may mod my stock exhaust in the future. Happy Trails...

I have a 2010 and an SCT 91-octane tune installed. The standard tunes SCT provides are for 87, 91 and 93 octane. You will notice a responsiveness increase with the 87 tune and may think its quicker, but I'm not so sure. Now the 91 tune most definitely provides a torque and hp increase that you can clearly feel. If 93 octane was available in CA I'd tune for that - but it isn't. Gas mileage with the 87 tune is the same. The 91-octane tune will get about a 0.5 mpg increase. Btw, the 2010's are rated for better mgp than the 2007-2009 and I must say your 21 highway mpg sucks. I average 22mpg with 60% highway travel. I've never been on a trip with the tune so I don't know what true mpg might be. I drive 75-80 mph. Good luck

Ya I was thinking about both also. I think? there may be a higher risk with the thing running right though. In any case, the stock air box - 2010 or 2011 - may not fit under the 2010 hood right and if so, I wouldn't be able to pass Cali smog inspection every 2 years. Upper manifold pop-off-n-on is enough of a PITA, never mind pulling the lower every 2 years.

I'm sure you all have been losing sleep over this... I'm answering my own original question of this thread. After looking at the bottom view of a 2010 and a 2011 upper manifold, it is clear this will not work. The ports are in a straight line on the 2010 but staggered on the 2011. Ah well...

Seeing that the original post was almost a year ago, the original poster may not even read this... Anyhoo... I have the 91-octane off-the-shelf SCT4 tune in my 2010 and it is faster and gets about 1/2 - 3/4 mpg better. It still costs a bit more on gas because of the increased 91-octane fuel cost. No theory chatter here - just the facts. I think it will do better on both counts once I get a better intake. Currently have stock parts with both tube-top-ports plugged and both snorkels removed from air box and an AEM dry-flow drop-in filter. Happy trails....

More findings... Sct4 is user-friendly once u get used to it; Waldo is exactly right - the stock tune is optimized for 87-octane; I think 87-octane in CA is about 86-octane. I say this because the 87-octane tune seems slightly better with 89 pump octane. Meaning, I think what sells her as 89 is really 88 - total guess; The 91-octane tune with CA 91-octane pump gas is nice. Clear boost over the 87 octane tune; I'd guess if sman83 ran 89 octane CA gas, it would be just as good with his factory tune; about 1/2 of an mpg gain with 91-octane tune. I may now go back and tinker with my intake some more. Maybe with the tune, I can get more out of it.

I'm replying to my own post. Got the sct4 tuner and installed the default tune into my California vehicle with no ill effects. I need to tweak it because the default tune only seems to fool the TPS and quicken/stiffen the upshifts in normal and full throttle driving. At this point, I don't feel any hp increase, and the fooled TPS makes you think the torque increased during normal driving, but full-throttle runs tells you otherwise. I'll reserve judgment until I exhaust all my tuning options. I think the device is not as friendly as it could be, but that's just my opinion. Others may think otherwise.

Back in the day on rear wheel drive cars, there was an easy way to check for broken motor mounts. Have someone you trust put it in drive with foot on brake and give it a little gas but DON'T MOVE THE CAR. You will look at the engine during this to see if the engine jacks up higher than normal. Do this again in reverse gear. You'll know if its not normal movement. Good luck
