HELP! just installed new pro-m car is a dog now

I just installed a 75mm pro m bullet on my car and it is a dog above 2krpms and idles rough now. What's going on? Do I need to reset the computer or something? I don't want ot have to put the stocker back on.

Is it calibtrated for the right injectors?

 

[Nottoofast50]

yes... i figured out it has a bad sensor... i put the stock one on it and it works fine... however it still feels sluggish

Pro-M sensors are calibrated with the Pro-M MAF housing. You can't swap a stock sensor on them and expect them to run right. You get to send the whole thing back to Pro-M, they will fix it for free if it is new & under warranty.

It is used and not under warranty...
