when i compared the omni ring to the factory, it was noticeably narrower (inside of ring to outside) when sitting one on top of the other.

 

I've had my Omni in for 4 yrs and no leaks

 

I also ran 1 for awhile without any problems.

 

Great recommendation. I reused the stock o-ring on my 50K mile set-up, and it worked great for about 3-4 weeks, but then it developed a really bad leak. New o-ring, boost leak test, and A-OK again!

 

I just swapped mine out today and I could also see a definite difference in the size of the two rings when I compared them side by side. The Omni ring is definitely smaller but I'm not entirely sure mine was ever leaking.

 

how do you guys pull the o-ring off

 

To bring this back I just got a evo 9 and I got a p0069 cel will a bad oring do this as well I also have a omni 4 bar thanks plus it only make about 15 psi

 

im gonna check mine for a leak it has the standard o ring it comes with

 

Just checked mine. Wasn't leaking but the oem o Ring was a "hair" larger.

 

Had an omni map sensor for close to 4 years on the supplied o-ring and it doesnt leak

 

Thanks thus will save me alot of time lol I hate boost leaks

 

Dumb question honestly but I wanted to make sure I am right on this.. When I install this sensor do I need to get a retune or should I still be fine? Just wanted to make sure I didn't need to get a retune.

 

You need to make adjustments in the rom for the car to run. This sensor requires different settings than the stock one. It's a quick less than a minute change.

Also I am local to you and can make the change and flash it if needed.
