I have bought myself a bbk 58mm tb and it didnt come with all of the necessary sensors. Supposedly i need a tps for it. and maybe something else. Who knows where i would have to go to get it?

 

You could just swap over the neccesary components from the stock TB if you have one. The TPS sensor should swap over and you may have to adjust it using either a voltmeter or a scan tool. The idle air control motor on the bottom of the tb should also swap over. However if you dont have them they should be available at a parts store. Most GM vehicles use the same parts so they should be easy to find and affordable.
