Just added a throttle body spacer and wow does the throttle work better. The bird hauls ass like you would not believe. Goes through gas like crazy but that is because I have a lead foot. All my stuff came from ebay for cheap. I got lowering springs but have yet to put them on because the bumper scrapes like crazy now. No more Pontiacs will ever be made so my bird is the last of a dead breed. If you got a bird take care of it!
