Haha that's weird. I saw a big decrease in trims going from a Rebel to OTTP, but not a vacuum increase.

 

I thought maybe it was just one of the couplers, but I don't see how a bad coupler could affect vacuum since its before the TB. I'll keep an eye on it though. I'm still not 100% convinced.

 

anyone order that aboveallmotorworks one? i got it off there and my kpa is reading way high lol...

 

What does the label say? If its different from stock then swap it out asap.

Wierd though, because I ordered that one before I found the GM number and it worked fine. Maybe they sent you the wrong one? I can't delete the grayed out area anymore due to the restrictions on editing old posts..

 

It might be working not sure on the label it's under my intake mani and def not taking it off at the moment hahaha. Think my baro sensor went bad on me now too like everything else reading 50kpa at idle fml.
