Default Which MAP Sensor?

I've reached the limit of my current Map sensor (2002 WRX) and need to find a decent 3 or 4 bar sensor. Is there a PnP solution - obviously I know the map will need adjusting once fitted but Ideally I want one to fit in the OE location.

the subaru 3bar sensor or the omni 3bar/4bar all go straight in.

what setup are you running to need the higher map range though - I'm guessing forged build/6speed/giant brakes/injectors etc?

3 bar map sensor will be fine unless you are looking to run over 2 bar of boost pressure,as above the subaru 3bar or omni one would be fine.SJ.

I'm running a forged 2.5 on syvecs at 1.6 bar I need to switch to the 3Bar to give a bit more headroom on the sensor and up the boost a little through the mid range.

Anybody know a UK stockist of the Omni sensors - I can't find a Subaru 3 bar sensor online?

Will they fit the loom and the Throttle body - I'm trying to tidy up the bay at the moment and adaptors hoses etc. are to be avoided!
