I definitely wouldnt put it on unless you get some confirmation from someone who is knows about this stuff. Here is a thread that discussed the Omni 4 bar map sensor. If you scroll down maybe email OmniUSA who responded on the thread.

From what I have read it seems that maybe the ULT shouldnt be used if boosting more than 10.94psi. Might be better off going with AEM if boosting higher.

 

any greddy guys running aftermarket map sensor?

 

Mugenrio is running the greddy pressure sensor.
He has the e manage ultimate but a roots supercharger.

 

man....i have the definite answer pm me if you wanna know how to get rid of the vtec dip... its such a easy fix

 

is the Greddy one just plug and play essentially?

 

I also couldnt find much info on the greddy Map sensor. Found what I think is the correct one but you will have to also buy the harness I think.

yeah, The Harness is required for GREDDY, its only $36.00 I just ordered both for my Meth Tune

 

Awesome. Look forward to your results! When does it all get installed tuned and dynoed?

 

Hope to install the Meth with the Berk HFC early OCT or Late Sept, and Tune & Dyno is either Nov 14, or 17th I am going to Vegas for 2 weeks mid October

 

Hmmm I'm running my CTSC @ 10psi with the Ultimate and after some days with the tuner getting the partial throttle done I still have problems with hesitation/bog more noticeable after long drives or driving hard. I wonder if a map sensor would be the problem.
