Your upper TMAP sensor is an original GM 2-bar, so no GMTU. That means the lower TMAP sensor is probably original also. Unless it's the upper TMAP that was recently replaced, and the lower is a Bosch 3-bar.

Does the gas door say premium recommended, or required?

 

I know I have the warm intake lol. I've read so much about this car and wish I had factory intake. Or I might custom fab something.. is that a good or bad thing about the different engine? How can I exactly tell what I have? I can take more pictures if you would like. Can I contact zzp and give them vin or anything?

 

well gas door says premium recommended/required. And I have that gm performance badge and yes I also could not find the Bosch TMaps but I am not sure if I am looking in the right place. If my top one doesn't have it that may have been the one that got replaced. Would it be worth while to call the dealership and ask? Would my upper tmap blow quickly if they put the wrong one in? Let's say in about 600 miles or so?

 

Just to show

 

All the SS have the GM Performance badge. So you have 2 labels in the gas door?

No, the sensor won't blow, but it cannot allow higher boost pressures.

 

Required means upgrade; recommended means stock. Where do you see required?

 

Gotcha. I only got the one sticker in the picture. Ok so probably no gmtu then. So I did some reading and one of the motors has a bigger oil pan and oil sensor maybe? Which when I was underneath looking at stuff I seen a sensor not plugged into anything on my oil pan. Is it a good thing I already have a new motor? Any way to know what motor I do have? Thank you guys for helping me through this. I got a new solenoid for bpv I bought Sunday that I am going to try. I didn't hear the noise the post was saying about vacuum pump but I'm not ruling that out until car is fixed. Will be doing boost check and vacuum also as soon as I can. Should I buy pressurized system or is smoke easier?

 

Ok, recommended, so no upgrade. I was typing while you were posting the pic

 

Sorry guys I thought I seen required. Just recommend.

 

Yes, the sensor for the Buick Regal is not used by our HHRs. Congrats, you got the LHU/LDK. It requires a good 6 quarts of oil, maybe just a bit more.
