Nope, if you go back stock you have to swap out the MAP sensor. Sensor can be changed in less than 5mins.

Also, i'd doubt your assumption. Most people likely don't know what a map sensor even is.
ordered AA5Z-9F479-B for $83 plus shipping from Tousley Ford. He says the number is
AA5Z-9F479-AB on the actual part just like the picture someone posted on the previous page. He pulled a few MAP sensors from ecoboost vehicles since he was curious about the 3 bar becasue he has a Focus ST and likes ecoboost performance.
He comparred several MAP sensors and couldn't tell the difference in them at all. I figured the 3 bar with the part number above would have 3 wires / bars / sensors going through the actual sensor part kind of like a MAF sensor has those delicate little bars in there that you clean.
Oh well I ordered the right part for a good deal now bring the XV1 tune LMS !!!!!!!!!

Do you think a 3 bar sensor holds more liquor than a 2 bar? OOPS...

Damn... I thought you were kidding... but you are spot on!!!! I even found one with 15%... and it attracts 85% stations like a sky hook!!!!

I would just wait until I had the tune.

Some of it is just hype! "I gots me a 3 bar sensor installed and the extra boost is crazy good:... LOL
I was actually the first to run one from what I understand. Then Darreli got one, even though Livernois didn't think he needed it ( back in late 2010 - early 2011). The problem with allowing the stock turbos to produce higher boost levels is the FRP. If you combine the 3 bar with Meth injection which in effect adds fuel, you have less fueling issues. Hopefully the new tune being developed will somehow get around that issue, but it may be fueling issues that are delaying the new tune's availability. Livernois doesn't want to sell something that may cause issues. They wouldn't give me their methanol tunes without having my system dyno'd in house... and I felt that was a very reasonable decision on their part. In fact it only came up because Rick knew I was spraying, when I asked for their 4+ to go with the other 2 bar tunes I had earlier purchased.

I always talk to Anthony with LMS about my LMS tunes and I beleive he told me they have been runing the XV1 on ecoboost vehicles in house and it only required the 3 bar MAP and a thermostat to run that tune due to it carrying the higher boost closer to the shift point or rev limiter. It made sense to me. Sounded like they may have it ready to release to everyone by the end of the year 
I'm excited about it I can definately feel the power fall off after 5k rpms after the boost bleeds off.

My boost didn't bleed off with Torrie's custom tuning. In fact that's probably why my FRP dropped as low as it did at high RPM in 2nd gear. That's also where my boost peaked.

4Dr is much more qualified to get into the nuts and bolts of fueling than I. Check for his write-ups. Basically it boils down to more boost=more fuel needed. Especially at higher RPMs.
