Bigger MAF sensor

So over the weekend my boy and I was working and cleaning our cars. We came up with the bright idea to change the MAF sensor from a 2007 Trailblazer SS and put it on my car. When I say my car was COMPLETELY different. Take off was much stronger and pulls much harder. The MAF is MUCH bigger than the one that comes on my car, so I was impressed.

The next day I started the car and felt a slight hesitation. I pulled off and noticed that the car had slight hesitations and pauses. I got to the freeway and put my foot down and had a huge hesitation, then it took off like a rocket. So here are my questions:

1. Is it safe to change MAF sensors from other cars?
2. Has anyone had any success doing this?
3. Am I damaging anything by doing this?
4. If anyone has had any success doing this, what MAF sensor did you switch to?

Now I am new to tinkering around with cars, so if this was a bad idea, don't clown me too hard.. lol
 


pretty sure you need to tune the new maf to the car. im quite surprised it even ran with it. ( or plugged in) id put the stock one back.
 
I won't clown you, but your can't just throw it on and "run it"

That car is not "programmed" to run that different MAF sensor. Though I'm sure its a similar MAF, its still not correct.

The only time you need to upgrade the MAF is when you outflow the stock one, which I highly doubt you because I assume the motor is all stock.

Just throw the stock MAF back in and be on your way.
 
Not exactly the case with diffrent platforms LS motors pick up decent power when upgrading to bigger MAFS, yes you need to tune but it ran because the stock calibrations arent that far off. You do however need a tune for this upgrade and definatley do not want to go stabbing the throttle. get tuned to run this upgrade.
