Oh GAWDDDDDDDDDDDDDDDDDDDD

Actually all is good. Biggest tip is to get the scalar set to key on engine off to your actual kPa. It was only a little richer than the 2bar at part throttle. Dead on at WOT. Drove great on the 2bar tune....I'll fine tune it tomorrow.

Delphi 3bar part number 12223861 sold by Speed Inc under the FAST brand and many others...great low end resolution.....don't waste your time or money on a 2 bar map like I did.

That's what I thought when I bought it. 2.5 would have been plenty for me, but it's not 2.5

What is needed to fit the 3 bar sensor you listed? Does it fit as good as the Cobalt sensor?

If you are using a 3bar, I wouldn't necessarily trust the little clips to hold any sensor in without leaking or blowing out. The best thing to do is tap a hose barb and run a line to remote mount the map sensor, although that would be a bitch in an fbody.
