Hey, i know nothing about the inards of engines and i'm slowly trying to learn, but could someone basically explain Tuned Port Injection to me. Keep in mind i know very little about the engine of a camaro. I have a '91 RS V6 so how would it relate to me, if at all. I know this is probably a waist of time for a lot of you, but any help would be appreciated. lol, i feel like a child, but i really want to learn about F-Bodies. Thanks

 

All u have to do is look in the Tech Articles.

Great articles aside from the fat that he says porting the MAF is a good idea and the TB bypass is a bad idea..I feel the same way except backwards. And, I think he believes TPiS too much..Esp. with the AFPR claims..Tt was written in '98..so things may have been different back in the day
