What 4 Bar MAP Sensor for MS3 PRO?
I have a GM 3 bar MAP sensor, but need a 4 Bar. Who sells a good 4 bar MAP sensor with connector? This will be for a MS3 PRO so external sensor.

I found this one on ebay, but it's a no-brand part, no idea if it's junk or a good part. DIY doesn't sell a 4 bar for the MS3 PRO, I already asked them if they had one and they said no, but they would make a note for the demand and consider it as a future product.

Does anyone else have a rec for this? I've been looking for something official-ish, but I've mostly been running into no-name ebay ones or 100 dollar ballenger ones. Wondering if anyone has a part number for an AC Delco one or whatnot...otherwise I may just get the 3 bar for now if I can't find anything legit.

I ended up buying a 3 bar from DIY for better resolution and I'm going to use the 2.5bar in the ECU for baro correction. I doubt I'm going to be pushing over 30psi anytime in the near future, if ever haha. DIY also sells the MAPDaddy one that replaces the stocker in the Megasquirt.
If you're looking for a GM style one, then it appears as though ballenger has some: https://www.bmotorsports.com/shop/pr...oducts_id/2134
Additionally, there's a brand called OMNIPower that seems to make them in the US. I was going to get one of theirs on ebay because i had a 15% off sale thing yesterday, but chickened out because I'm not ballsy enough to save 25 bucks on a sensor this important and have seen tons of knockoffs on ebay. Looks like a few reputable tuning sites carry their sensors so it should be all good.
Here's the link to their official site though:

I'm gonna correct the resolution comments you keep making: on a good quality modern map sensor and good quality modern ecu, I have yet to see any ill affects from 4bar vs 3bar. at all. If someone has, you got my attention, please share.
I say this because you make it sound like 4bar will have bad resolution and create issues. If you don't need it then of course go for the 3 bar, just don't make up issues out of thin air.
