When I bought my 96 GSR I was cleaning the trunk and found a little box and inside was a ProBoost Platinum performance module. I have no idea what it does or where it goes. Its a little black box the size of a credit card with two red and two black wires coming off of it.

So what the heck is it, where does it go and what does it do? haha

 

its proly a resistor that tricks the ecu into thinking your IAT is always 35 degrees F and runs rich for a lil more power
chuck it IMHO
they dont work

 

I agree. Ditch it.

 

I figured he had it because the C1 that came in it had a S/C on it so I figured he ran it on there to get the SC to keep from detonating
